You are a fired heater designer and you are supposed to design a direct fired heater for a refinery process. You are clearly required by client specifications to design with an average heat flux density of 12,000 Btu/h.ft2. Now the question is this: How much margin is a good margin Read more…
Different Erosion Categories Faced in Industry Erosion in industrial systems refers to the gradual wear and tear of materials due to mechanical action or chemical reactions with fluid particles. It can be broadly categorized into: Liquid Droplet Erosion Liquid droplet erosion is a type of erosion which needs to be Read more…
Thanks to all of you who have participated and supported me, we, together, successfully held the webinar “Process Direct Fired Heaters; An introductory lecture” alongside a very useful and engaging Q&A session at the end and spent one hell of an evening together! You can see the videos of the Read more…
To properly control the combustion air, O2 and CO must be measured at the top of the radiant section where combustion is completed, regardless of the burner loading. Note that O2 and CO will coexist within the flames, where the temperature may be as high as 1200˚C. Low NOx burners Read more…
The steam methane reforming (SMR) process can be described by two main reactions. The first reaction is reforming itself, while the second is the water-gas shift reaction. Since the overall reaction is endothermic, some heat input is required. This is accomplished by combustion of natural gas or other fuel in Read more…
Process direct fired heaters are super important in a lot of industrial processes, but sometimes, things can go wrong. Here’s what can cause them to fail: Now, let’s look at some signs that the heater isn’t working as efficiently as it should be:
