In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Flame impingement on a cold surface can lead to incomplete combustion, meaning soot and CO. Yet... all gas stoves I know have some degree of flame impingement. I tested my gas burners over the weekend and got some interesting results... I have a big honkin' center burner that I figured would produce the most CO but it actually barely had any, whereas some of the smaller ones had in the range of 100 ppm. And this is for an unvented appliance (range hood notwithstanding.) This was without a pot filled with cold water on top; I'm sure things would be worse with, so I'm almost afraid to test. There's no way to alter the fuel-air mix on these except the big honkin' one.
Ah, well... should have gotten an induction stove, but I likes the flame. Anyone else take a combustion analyzer to their stove or other common appliance?
