Actually i have fired big burners to small with everything from crude oil, coke gas, pulverized coal, wood chips,natural gas, propane, diesel.etc. My background has a lot of combustion in it. The largest burner that i have been around was about 120millioin BTUH in a pulp dryer, it had a NG backup that was 6" at 60psi. it actually fired on coke gas most of the time. The pilot light was a 4 million btuh NG burner, the fire ball was about 15 ft in diameter and 65 to 75 ft long.

For bronze i would need to come up with a source for the raw scrap and from my understanding it would be hard to keep the product consistent.
