I am working on building a big cooker out of a home oil tank laid on it's side with a cement block (possible firebrick lined) fire box with a large waste oil burner. Now what would be the best way to build the burner, I'm thinking I need to take one of the large pressure tanks I have and set it up to hold 10-20 gallons of waste oil and connect it to a compressor. I am not sure how to build the burner itself besides a nozzle and a blower of some kind. I want to be able to heat up 100-200 gallons of product in a reasonable period of time with as big of a burner as I can build or a pair of big burners and be able throttle down to a low boil. So let me hear what your thoughts are and what you think I could do for construction of my burner and pressure vessel.
How many BTU's are you looking at to make your cooker work?
