Having a new Boil Kettle made out of a spare tank we had laying around. The aim is a 7BBL kettle. It will be direct fire, using 2 225,000 BTU propane burners, similar to the HPMAX-2. It will have a 2" bottom drain that will be wrapped in ceramic insulation to prevent scorching. A side port with a racking arm to draw off wort, and a whirlpool return arm. It will have a manway access hatch on the top, which is not currently shown in the drawing.
Doubts I have are if we should be using a enclosed firebox with those burners or is just heat shielding sufficient? And placement of the flue exhaust, should it be higher up, lower down? I plan to have a baffle plate placed in front of the flue exit to help retain the heat, but not really clear on what form/shape that should take either. Are those burners up to the job? or should I be looking to use a forced air burner? If so what size?
Attached is the design we have come up with, any feedback or comments would be welcome. All measurements are in metric.
