Safety is a Choice

Well, hey there everyone. I figured I might break up the monotony of the ongoing Pulse Fire series and talk a few moments to you about safety. I can hear the groans now but hang with me as we here at HEAT Combustion Solutions, LLC take safety extremely seriously.

I realize that the reaction to that statement may be, “Oh jeeze… here we go… another goofy company President spouting off about safety.” Let me correct those that are skeptical and point out that while I am indeed the President of HEAT Combustion Solutions, LLC, I also consider myself a member of the team and continue to go to job sites, just like the rest or our Team. I’m no better than any of the other Team members and must abide by the same rules. In that sense, I feel very passionately about safety.

This week has been a very educational one for myself and another Team member as far as safety is concerned. We have been doing work off and on at a refinery these past few months working on Cracking Furnaces.

Pulse Firing – Part Five: The Everyman’s Guide to Pulse Firing Control

When last we left this subject, I indicated we would discuss the nuts and bolts of how in fact does the control work for this Pulse Firing. Well, I’m not nearly smart enough to get into the “nuts and bolts” of the control, so to speak. I’m going to enlist the help of a guest blogger, Mike Shay, here at HEAT Combustion Solutions, LLC for the next installment. He’s a controls guy, much more so than me when it comes to the technical qualities of Pulse Firing Technology in as much as he will get into the algorithms, saw tooth graphs and…………….. sorry, fell asleep just talking about that.

Anyway, here we go with what I term “The Everyman’s Guide to Pulse Firing Control.”

Pulse Firing – Part Four: Key Equipment Hardware

I guess we have laid enough ground work up to now in the previous three installments to get to the question, “how does this Pulse Fire thing work?

In this installment, we will focus on the key equipment hardware.

There are two types of Pulse Fire systems. Those being “Heat Only” and “Heat/Cool.”

The system designed for Heat Only has limited flexibility as it is not able to provide a controlled cooling function utilizing excess air.

Pulse Firing – Part Three: Radiation, Convection and the Utilization of Both In Pulse Firing

As I perused the last two blog posts to refresh my memory on this Pulse Firing topic, I thought it might be a good idea to step back somewhat and review the methods of heat transfer most germane to this topic. The two methods being:

1. Radiation
2. Convection, or Forced Convection for our purposes

There are gobs of information out there on heat transfer and such and we could spend the next six months just discussing that, but in the interest remaining on the topic of Pulse Firing and not getting too far out in the tall weeds thrashing around, I will attempt to boil this down. Keep in mind that this is in no way intended to be a comprehensive discussion on these two methods of heat transfer.

Let’s start off with the basics. I would like to preface this with the statement that most of you will know this, but I think it important to just define them for the sake of the cause.

Pulse Firing – Part Two

This is part two of our continuing discussion on Pulse Firing and the issues it addresses in these three key areas:

-Poor temperature uniformity in the furnace which results in sub-standard product uniformity

-Inadequate turndown of the system in total

-Excessive Fuel Consumption

Neither of these issues exists solely by itself. They are all interrelated. Until the introduction of Pulse Firing technology, it was not possible to address these three issues at once. One still had to give up something to gain something else.

Pulse Firing – Part One: A Practical Solution to Furnace Uniformity

I would like to discuss, briefly, Pulse Firing Technology and the benefits to temperature uniformity in furnace applications. Pulse Firing has been around for many decades now and its benefits are well known and documented. The technology was introduced and perfected in Europe and is most prevalent there. However, here in the United States, it has slowly gained traction since its introduction in the early 1980’s.

Manufacturers in the industrial heat processing industry got a slight taste of this, at that time, “new” technology if they had purchased a gas fired furnace from a European Furnace OEM. However, its first successful commercial introduction to the United States by a domestic burner company took place in 1985 via a partnership between Hauck Manufacturing and Krom Schroder.

Introducing New Partnership – Webster

In an ongoing effort to be the folks that can provide solutions and equipment for all things combustion, we are very happy to announce a new “partnership” with Webster Combustion.

I say “Partnership” as our working with Webster is viewed by both entities as being partners and not just that of a Supplier/Distributor model.

On a company level, as well as a personal level, this new relationship is very exciting.

Effects Of Moisture Content of Material For Aggregate Rotary Drying

We here at HEAT Combustion Solutions, LLC have been involved in the Rotary Drying of Aggregates for over 20 years. In that time, we have leaned a lot. Sometimes painfully but that is a completely different bunch of stories.

As the calendar indicates, we are coming up on the end of February. As spring is now in sight, Asphalt plants in the colder regions are preparing to fire up for the road construction season. The early part of construction season is usually accompanied by cool wet days as winter transitions to summer. With that in mind, I want to zero in on the effects of moisture content in the aggregate and how that directly impacts the burner and plant capacity.
