Tubular Ring burner

[hugenjapan]

Anyone know of any good tubular ring burners? I'm making a 36 gallon pot that drains out from the centre and can't use a regular burner cause it will scorch the wort in the drain pipe.. I'm looking for something around 10"-15" dia. I thought about making my own but everyone says it's hard to make a Venturi and get proper propane to air mixture. If anyone has any ideas it would be greatly appreciated. Thanks!

I have seen people use these and plug up some of the jets to match what they have under the kettle.
