Heat Treat Tips: Effect of Exhaust Gas Temperature vs. O2 on Efficiency

During the day-to-day operation of heat treat departments, many habits are formed and procedures followed that sometimes are done simply because that’s the way they’ve always been done. One of the great benefits of having a community of heat treaters is to challenge those habits and look at new ways of doing things. Heat Treat Today‘s 101 Heat Treat Tips, tips and tricks that come from some of the industry’s foremost experts, were initially published in the FNA 2018 Special Print Edition, as a way to make the benefits of that community available to as many people as possible. This special edition is available in a digital format here.

Today, we offer one of the tips published under the Combustion category.

Effect of Exhaust Gas Temperature vs. O2 on Efficiency

Tuning a burner properly is important for safety. Tuning can also have a significant effect on efficiency in some but not all cases.

The efficiency of a conventional cold air burner varies significantly with the amount of excess air (related to % O2 in the exhaust products). Since a cold air burner does not use the exhaust gas to preheat the combustion temperature, the exhaust gas temperature is essentially equal to the furnace temperature. For a cold air burner operating at a 1,850°F, reducing excess air from 20% to 10% (reducing O2 from 4% to 2%) will increase efficiency by almost 5%.

Modern high-efficiency burners use the exhaust gas to preheat the combustion air as it enters the burner. Therefore, the temperature of the exhaust gas leaving the burner is significantly lower. The lower the exhaust gas temperature, the smaller the effect of a change in excess air on efficiency. For example, a self-regenerative burner operating at 1,850°F may have an exhaust gas temperature around 480°F. In this case, reducing excess air from 20% to 10% (reducing O2 from 4% to 2%) will only increase efficiency by about 1%.

As a general rule of thumb, reducing exhaust gas temperature by 180°F will increase efficiency by about 5%. So while proper tuning is important for many reasons, it does not have a significant effect on the efficiency of burners with advanced heat recovery systems.

Controls Upgrade for Heat Treater to Medical, Auto, Defense Industries

Two projects involving controls upgrades were recently completed at a Dayton, Ohio-based, heat treating company that serves the medical supplies industry, as well as automotive, defense, firearms, and construction sectors.

Super Systems Inc. (SSi), located in Cincinnati, Ohio,  announced two upgrade projects at American Heat Treating in Dayton, Ohio. Controls were upgraded on a Beavermatic integral quench furnace that included a Series 9205 with a 12.1” HMI for atmosphere and temperature control and datalogging, a Series 804 for oil quench temperature control (heating and cooling), and other ancillary items. A second project included a controls retrofit of a Lindberg 3000 SCFH endothermic generator with an SSi AutoGen control system.

“Our long-range plan was to upgrade the controls on the Beavermatic, but when the old controller failed without notice, Super Systems jumped into action and did the complete upgrade project quickly,” said Van Hatcher, Instrument Technician and project leader at American Heat Treating. “Our endothermic generator has been operating with the new SSi AutoGen controls with no issues since commissioning. We look forward to the operating cost savings that come with the automated turndown features.”

Heat Treaters, First Article Inspection, and AS9102 Compliance

 

Source: Paulo

 

Aerospace, automotive, medical and all other industries require FAI — first article inspection, the systematic inspection of new parts to ensure they’ll perform as designed. This includes parts that are subject to heat treatment, which adheres to its own process-specific set of FAI requirements.  This week’s Technical Tuesday feature provides an examination of the exhaustive FAI documentation process for heat treatment of aerospace parts and why it’s so critical.

“Heat treatment almost always distorts parts—it’s the price that comes with enhancing mechanical properties. First article inspections help heat treaters and customers determine whether specified processes will result in acceptable amounts of distortion or if design, material, manufacturing and processing specs need to change.” ~ Paulo

40 Under 40 Highlight: Michael Elmore

In 2018, Heat Treat Today introduced one of its most popular features, the 40 Under 40 Awards for young, up-and-coming talent in the North American heat treat industry. Click here for the 2018 recipients. Heat Treat Today is posting occasional features of some of the 2018 recipients in anticipation of the 2019 40 Under 40 awardees to be presented in September (nominations are being accepted here). First on our list is also one of the first to have been nominated.


Michael Elmore

GKN Driveline

Heat Treat Engineer

Michael Elmore was nominated from within GKN Driveline. The following was provided by the nominator:

Michael continues to prove himself many times over by working to improve the heat treat and processes at GKN. He shows himself to be knowledgeable and takes great pride in what he does, working well with everyone in the department and always willing to help out. The heat treat department at our facility has already reaped rewards for his hard work. Michael’s work ethic is practiced daily, garnering him a great deal of respect.

 

Michael Elmore started at GKN Driveline right out of college with a little bit of familiarity with the territory, having worked for the company during a summer internship. That experience led him to shift his academic focus from design-based engineering to the type of process improvement work he encountered in the heat treat department at the automotive components manufacturer’s North Carolina facility.

“When I came to GKN, I fell in love with heat treating,” said Elmore. “I expected this to be a puddle and it turned out to be more like jumping into an ocean. There’s so much more to it than I expected.”

Michael worked with Jack Gerochowski, head of the heat treat department, whom he describes as “a heat treating genius”. He spent time in the metallurgical lab with Gerochowski, learning all about the process. GKN was in the process of creating the position of heat treat engineer and Elmore was the first to be hired. Four years later, “I’m still finding out things I didn’t know. It goes deeper and deeper the longer I’m here, never hitting the bottom of what can be learned, done, or explored.”

As an engineering student, he expected he would be doing a lot of design work on the field, but he states the work he does now with heat treating provides “more immediate satisfaction. We can help the company save money. GKN already has a top-notch heat treat department. I didn’t arrive and make any huge improvements — just a few tweaks here or there, like increasing checks, decreasing possibilities of a spill.”

The North Carolina facility employs over 1,800, with 25-30 in the heat treat department. Michael said the next new project in line at GKN Driveline is in Non-Destructive Testing using their first NDT equipment recently purchased from Forester Instruments (Pittsburgh). The heat treat department hopes to develop a new way of testing gears to eliminate inconsistencies, save money, and free up the metallurgy labs to do more exploratory work.

Asked what he would advise the next generation of heat treat professionals, Michael offered: “The possibilities are endless with heat treating, an industry that is instrumental in every aspect of life. There are broad opportunities and many different fields to work in. It’s very satisfactory being a part of making things better.”

He added, “I couldn’t do anything without all the support and training from Jack, and also Greg Cook, GKN maintenance manager for the heat treat department who nominated me for the 40 Under 40.”

Transcript: Jim Oakes

The following transcript has been edited for your reading enjoyment.

On this episode of Heat Treat Radio, we’re discussing data.  If there is one thing that is significantly changed in the Heat Treat world in the last decade, it’s the quantity and quality of data.  What the heck do you do with all the data?  How do you collect it?  How do you decide which data sets the capture and after you capture them, how can you learn anything from them? Data, data everywhere, and not a drop to drink!

Welcome to Heat Treat radio.  I am your host and publisher of Heat Treat Today, Doug Glenn.  Today, we’re going to talk to one of the industries leading authorities on data, Jim Oakes from Super Systems Inc.  But before we do, why don’t you take a little cyber trip over to www.heattreattoday.com and see all the data we have there?  We’ve got aerospace heat treat data, we’ve got automotive heat treat data, we’ve got medical heat treat data and energy heat treat data as well as general manufacturing heat treat data.  In fact, we’re adding at least one new piece of heat treating data every day.  On Tuesday, we publish technical content.  We call it ‘Technical Tuesday.  If you’re a manufacturer within in-house heat treat, we’re pretty sure you’re going to find www.heattreattoday.com really helpful.

Before we get started, here is a word about this episode’s sponsor:  Today’s Heat Treat Radio is brought to you by Dry Coolers, designers and builders of industrial cooling systems and the professional engineering services surrounding those systems.  As a leader in the heat treat industry for decades, they’re located in Oxford, Michigan and supply cooling systems for the aerospace, automotive, medical and energy industries, plus many others.  If you have any industrial cooling needs, call Dry Coolers.  You can find them on the web at www.drycoolers.com or by phone at 800-525-8173.

Doug Glenn (DG):  Let’s get started on today’s topic — data. Our guest is Jim Oakes from Super Systems Inc.  Hi, Jim. Take a minute and introduce yourself to our listeners.

Jim Oakes (JO):  Hi, Doug, this is Jim Oakes with Super Systems. We’re a technology provider for the heat treating industry. We focus on sensors, controls, and software for the thermal processing and heat treating industry, and we’ve been doing that for over 20 years now.

DG:  Jim, how many years have you been in the heat treat industry?

JO:  15 years.

DG:  Over the past 15 years, what impresses you about the way we are using data now as opposed to the way we used it back then?

JO:  Well, a couple things, actually. My introduction to the industry was actually longer ago than 15 years. I started in an internship, and oddly enough, at that internship — it was for a technology provider in the heat treating industry — I was involved in doing data capture from a PLC at a Timken plant in Gaffney, South Carolina, and that was 25 years ago. Data acquisition has been happening not just in the heat treating industry, but in manufacturing for a very long time. What’s really been changing though, if you look at the last 10 to 20 years, is that the technology is lending itself, because of cost, both from a storage standpoint and processing standpoint, to really being accessible everywhere. You have more information that is coming out of microprocessor controls or PLCs or programmable logic controllers throughout the shop floor. Whether it be a piece of thermal processing equipment or a cooler or anything that is on the shop floor, we have tons of information that is becoming available. Before you might have been worried about how you would store all that information, but that is a thing of the past. The amount of information, and actually making sense of all of it, is where the challenge lies today, certainly not collecting it.

The Evolution of Data Collection

DG:  Ten years ago, are you seeing us collecting anything now that we didn’t collect then? Are we collecting more stuff than we were collecting back then, and if so, what are we collecting now that we weren’t collecting before?

JO:  That’s a great question, Doug, because back then a lot of the data was very specific and focused on process-related information. Now, there is additional data that is being collected that can be used for some predictive modeling, if you will. It’s not just proof of process that meets the industry requirements. Your customers were expecting that if you used a heat treatment process, then you had to really prove you performed that. Well, that’s a thing of the past. Of course, any data acquisition system that you have today, or anything data-related is going to provide you with that. But now there is more data, so on any day, in any heat treat facility, captive or commercial, I’d say there are 750,000 to well over a million data points that are being collected. Honestly, most people don’t even know that they’re collecting all that information. Their laser focus is on that one specific requirement. All that information that you can have is coming from these microprocessors or PLCs, so the amount of information today versus what you were gathering way back when is really one of the biggest differences.

DG:  What are some of the technologies that have driven that change so that now we can collect more?

JO:  A couple things. Standardized protocols have been around for capturing data, so you have to have a mechanism to get the data from all of these different pieces of equipment. That’s one piece. It’s existed for a long time. But if you think about it, if you take the shop floor today versus 10 years ago versus 20 years ago, there is a PC everywhere now.  You have a networking infrastructure that exists that maybe wasn’t there 20 years ago. Maybe you had a limited number of people that would be able to absorb that information and utilize it. Today, everyone is using a computer. Everybody is using a hand-held device. Now, all of a sudden, that information is readily available to lots of people, and that’s where the difference is. Not only do you have the networking infrastructure on the manufacturing on the shop floor, but you also have the technology that is available to everybody. Computers are everywhere.

Sensor Technology

DG:  One of the contentions I have is that the reason we’re able to gather so much more data now is that we’ve had advances in sensor technology. Maybe you can address this a bit.  I think there are things we are capturing now that we weren’t even able to capture before because of advances in sensors, whether it be IR sensors, or whatever.

JO: Yes, you’re right, Doug. If you look at the amount of information that is readily available, it is because of the technology that is available to capture it. There is all this sensor technology, whether it’s a limit switch identifying a basket or a tray moving to a specific location, or an infrared device that is used maybe for just measuring temperature on the outside of a furnace shell or an infrared analyzer used for analyzing the gas inside the chamber where the parts are being heat treated. Now you have the ability to take that additional information and use it for a decision making process.

And now you have all this data. Nobody is concerned about the amount of information you’re storing. Nobody ever says, “Well, we’re not going to have that much space.” The problem is people and time in actually evaluating all of the data. No doubt, using a sensor to monitor vibration of a pump or motor, or looking at the current usage, or looking at gas usage — the list goes on of the amount of information you can gather and this is because the cost has gone down. Each of those specific devices are now lower in cost and reasonably achievable from a data capture standpoint.

DG:  We might describe it as to say something like:  In the past, we used to put all the sensors inside the furnace, as you mentioned, to validate the process and things of that sort. It seems now that, because of cost of sensors and things of that sort, the fact that you can gather all this data and actually do something with it now, that we’re getting sensors on the outside of the equipment to make sure not that just the process is validated, but that the equipment is also validated, if you will, so that we can see troubles coming and that type of thing. Do you agree?

JO:  Yes, there is no doubt if you look at some of the benefits of what we see in the heat treating industry today. Of course, operational efficiencies are important. Now you’re taking the data that you’re gathering, again it’s not going to just prove that you’re running the parts properly, but you’re able to make better decisions from an operational standpoint. You can look for better load planning, you can look for reducing time between loads or gap time between loads and identify what’s causing those. The other thing is using this information for preventive maintenance. The equipment manufacturers are doing a great job with providing preventive maintenance programs and it is because of the sensors and the data acquisition systems that you are able to even just locally to that piece of equipment or gather from a plant-wide standpoint. There is no doubt, that some of the biggest benefits are from doing the data capture and then having this different sensor technology that allows for the preventive maintenance programs that can be put into place.

DG:  Isn’t that, in fact, where huge benefits can be gained, in the area of preventative maintenance?

Preventative Maintenance

JO:  Unplanned downtime is a huge cost component in heat treating. Anything you can do to manage the up-time of your equipment is beneficial. Of course, planned downtime gives you an opportunity to work with customers, work with the product that is flowing through your facility as well as managing the incoming parts that you might need for that equipment. So it’s a huge benefit. You can still do preventive maintenance programs that are in place; it doesn’t have to be with new equipment. You just have to be smart about the things that are important to that equipment and then utilize that data. I always say that data acquisition is very underutilized when it comes to maintenance. The maintenance department is usually one of the busiest groups within the thermal processing industry. A lot of domain knowledge goes into the equipment, but they have a lot of this information that is readily accessible to them, so if they could look at this information and anticipate that fan is going to fail, that motor is going to fail, that there is a short on your electrical elements, or whatever that might be, you’re going to be able to plan for the downtime. That’s going to help from an operational standpoint as well as reduce the amount of time that that furnace might be out of commission.

DG:  And when you’re not planning ahead, when you’re responding to fires rather than preventing fires, so to speak, it is usually the maintenance guys who catch the brunt of it.

JO:  Yes, that poor guy walks into work every day dreading work because he’s got a crisis on his hands every single time. If you can prevent that crisis, so he can plan to do something, it’s a totally different work environment.

Let’s take a quick break here and remind you that additional support for today’s Heat Treat Radio episode is being provided by Dry Coolers. If there is one thing we know about thermal processes, it’s that things get hot, and to remove that heat from critical areas, you need a system that is reliable, and if necessary, designed for your specific needs. The fact is, Dry Coolers has been custom designing and providing standardized units for decades, and they have the staff and experience to take care of any of your industrial cooling needs. If you’re a manufacturer with in-house heat treating and you need an industrial strength cooling system, make you first, and only call to Dry Coolers. You can look them up on the web at www.drycoolers.com.

Now let’s get back to our interview with Jim Oakes of Super Systems.

DG:  Where are you seeing data being used well?

Operational Benefits of Data Collection

JO:  The people that are taking advantage of the information are of course meeting the industry requirements. They are staying on top of things like CQI-9 or NadCap requirements from a data collection and meeting the customer requests. That is the foundation. I always say that in a lot of cases, that is a big driver for electronic data. But the people that are really taking advantage of that are using that information for operational benefits. Operational can be both from a maintenance standpoint as well as just improving your overall operations.  You’re looking at, “Why do I have downtime of two hours between loads on this particular piece of equipment?” So now, instead of using somebody to go search the shop for, and walk out and get a paper chart, you now have people that can actually evaluate the downtime between loads. You can look at gap times and identify what the issue is. Is it because I don’t have enough fixtures? Is it because I don’t have enough labor? The labor market is tight right now, so you want to use something that is going to provide you with something to maximize efficiency with what you have. Challenges might be your labor or might be your equipment. Are you making the most of your equipment? You can look at that data. You have tons of information. If you can evaluate that, it gives you an opportunity to make better decisions. That is one area.

The other area is, how can you utilize the data and push that out to all your people. Let everybody look at this, but only give them the pieces of information that are important. The maintenance department is going to be interested in maybe the percent output, the current going to the electrical elements, vibration, or water temperature. That information is relevant and if they could isolate that information, they can sit down with their cup of coffee in the morning and they can evaluate this information. Before they have to react to all the firestorms that they have in front of them, maybe they can actually plan for some preventative maintenance activities based off what the data is telling them. The right information to the right person is really critical. The people that are doing this are the ones that are really taking full advantage of the information that they have with a SCADA package.

DG:  Is there someone out there that is actually doing it?

JO:  Yes, absolutely! There is no doubt about it. People are taking resources, and instead of being reactive and trying to find stuff on the shop floor, they are using the system to identify, answer customer needs and then create those operational efficiencies. People absolutely, no doubt, are taking advantage of that. They are looking at shortening time between loads, notifying users when loads are done so they can get the parts out and then put new parts in. This is happening with mobile devices and/or emails so that the right people are notified at the right times.

DG:  Give us the lowdown on what SSI is doing in this area.

The SSI Data Capture

JO:  Our foundation provides us the ability to provide information everywhere. This starts with the sensor and taking that sensor data into a controlling equipment, whether course microprocessor control PLC. But you need to make that readily available so that people can make decisions quickly. Proof of process is one thing of course, but so is giving access to information, whether by mobile device or a messaging system. So we’re taking all of the information that we’ve already done in the past and providing that into the technology that people are utilizing today. We see huge opportunities from being able to go through the existing data that’s there, and then look at better ways to capture data based off the technology that is becoming available, whether it’s how we capture usage of gas or usage of electricity or just process-related data to make sure that the right person is getting the right information.

DG:  Many of the folks reading this article are manufacturers with their own in-house heat treat plants, and I’m guessing that many of them are wondering what they can do to move in this direction. What should these folks do next?

JO:  First step is to do an inventory of the equipment and be realistic about what data you can get out of them, highlight the drivers, meaning what are your business drivers for capturing that information, and then at that point decide if it is just the infrastructure from a data acquisition standpoint or, if you want to get some bigger bang for your buck, maybe you want to make an investment in some equipment that is technology down at each piece of equipment level, to capture that so that you can realize the gains based off of capturing that information.

DG:  If a company wants to move in this direction, must they go cloud-based?

The Cloud and Security

JO:  No, definitely not. The cloud is a tool that allows basically data and information to be stored externally. The reality is a virtual server in many degrees can potentially be a cloud-based system, but it doesn’t have to be. A large number of the installs we have are storing information locally and then transferring data to the cloud for backup recovery.

DG:  Address cloud-based security, if you would.

JO:  It is a huge topic from a security standpoint and I would say that most of the companies that use the SCADA packages are on-premise. That is not all of them, but most of them are. This means that if you are on premise, you have a private network where it is not accessible from anywhere unless you create that tunnel into that private network using virtual private network. That’s what you refer to as on-premise. Then you have cloud-based system, which is really just pushing that information up to a server form which provides access into it. Of course, there is a security aspect regarding accessing that information. A strategy has to be put forth that prevents external access to that information. In many cases, if you decide that you’re going to go to a cloud-based system, you’ve already thought through that and you’ve probably already transitioned some other systems to that. Anyone that is going to a cloud-based system has some security requirements to prevent any illegal or unwanted access.

DG:  Jim, thanks for your time.

JO:  Doug, thank you for having me on Heat Treat Radio. I really appreciate the opportunity. This topic is important to us here at Super Systems. As a technology provider to the industry, we really like to get the word out there about what types of things are coming, whether it’s making data accessible at the hand-held level, or helping make decisions, it is something that is near and dear to our heart and that is because a lot of our customers really find this necessary. I appreciate you spending the time with me and I really look forward to having discussions around this in the future.

Industrial Gases Supplier to Build 2 Air Separation Units, Increase Bulk Production

The leading U.S. supplier of industrial, medical and specialty gases recently announced plans to build two new air separation units (ASUs), one in the Minneapolis/St Paul area, and the other in Fairless Hills, Pennsylvania.

Pascal Vinet, Chief Executive Officer of Airgas, Inc. and Air Liquide Executive Committee Member

Airgas, an Air Liquide company, projects that the two new ASUs will increase bulk gas production in the Midwest and Northeast and complement Airgas’ strategic independent supply network throughout the United States. The two new ASUs, along with previously announced production facilities under construction in North Carolina (on-stream late 2019) and Southern California (on-stream early 2019), will ensure access to vital supply of atmospheric gases, further enable supply chain efficiencies, bolster network reliability and provide capacity for continued growth.

“With the construction of these two new ASUs, Airgas will deliver on our Air Liquide integration strategy to grow our independent production of bulk gases, to gain efficiencies in our dynamic supply chain, and to deliver product supply reliability to our customers,” said Pascal Vinet, Chief Executive Officer of Airgas, Inc. and Air Liquide Executive Committee Member.

The new ASU near Minneapolis/St. Paul, Minnesota will enhance the company’s gas production to serve growing needs in the Midwest, ensuring long-term reliability of supply and enabling ongoing efficiencies in support of its merchant, packaged and on-site gas customers. Permitting is ongoing and construction will begin in 2019 with operations expected to be on-stream in 2020.

In Fairless Hills, Pennsylvania, a new ASU will increase Airgas’ production capabilities throughout the Northeast and Mid-Atlantic regions, particularly to support major bulk gas markets including Philadelphia and New York City. Airgas will build this ASU on a former industrial site to be redeveloped under Pennsylvania’s Land Recycling Program (ACT 2). Construction is underway and the ASU is slated to be on-stream in early 2020.

Each ASU will produce oxygen, nitrogen and argon for use in customer applications such as food chilling and freezing, metal fabrication, blanketing and purging, and combustion enhancement. In addition, the ASUs will produce medical grade oxygen to supply to hospitals, nursing homes and research laboratories as well as food and pharmaceutical grade nitrogen.
