Burner Circle Diameter

You could measure the circumfrenece of the burner circle and divide by pi to determine the burner circle diameter. Or multiply the radius by 2.

Please provide more info and I will help you with this. As much info as possible is important.Application, fuel, emissions, btu input, fire box etc dimensions.

sorry about that, it's a fired heater, a vertical cylindrical one. The thing is, I wasn't actually looking for one answer, I was wondering if it was possible to make a program that calculates the burner circle diameter just by inputting the number of burners and their heat releases, and, of course, the type of fuel. My superior asked me that, and I don't have a clue how to do it, or if it's even possible.

Some training is required, then? It's time to get the supervisor to demonstrate how to do it. Bluff is an important business skill.........

The fast answer is no there is no set sizes. However there is linearity if conditions are similar as the input increases. Are you manufacturing this equip. if so I can give you the name of the best company to help you. You can go to webster-engineering.com. and compare their burner head domensions. Understand that the burners that you will be looking at are for boilers with reasonable back pressure but the heat release area of the heads may help you. What part of this wonderful world are you working in?

Many factors involved. Tube circle, Burner circle, vertical height, Firing Rate, API minimum distance BC to TC,

Contact or GOOGLE burner mfg's/ like John Zink or Zeeco they can provide minimum distance between burners to prevent flame interaction.

thanks everyone, i just wanted to be sure it is an almost impossible task, i mean there are so many things that you have to consider when doing something like this, i don't know maybe he (my superior) just wanted to keep me busy for 2 weeks, since he won't be around for this period of time. i'll take a look at what some of you told me to, but i'm pretty sure nothing's gonna come out of it, this ain't a cake recipe, that you can just throw the things you want and bam! it's done. it take years and years of experience to really get the job done correctly. but i'll try to give him something so taht he won't think i'm a total slacker lol.

btw, the fired heater is for a petrochemical company. But we also provide fired heaters for celulose companies (the black liquor section)

thanks again

Get the supervisor to do basic training in how to do the task. That's part of a supervisor's job!

Hi, takui-jp!

Your best reference may be to use not only the boiler type you have at hand, but also the injectors you are currently using, both fuel and steam and the flame type you wish to produce.

Check out the manuals for your boilers. The number of burners and ancillary/combined injectors, type of plastic liner, the size of the firing chamber, the fuel being burned, and the desired super steam production all figure in to the eventual burner size and are all clues that you can remember after reading about it in the manuals.

You already know that too small a flame diameter will result in a cold boiler and too great a diameter or length of flame will overheat or damage the boiler. When you monitor the boiler or change out the injectors, the settings have to be checked to be certain they are correct.

Some injectors will have markings on them and/or come with specs from the manufacturers.

This is not a silly task. It's a serious learning task. You are being asked to familiarize yourself with your tools.
