Black powder

post #1 of 14
Thread Starter 
The cast iron box in which I put my wood in my big block is covered with a black powder on the bottom and sides. It is very hard to wash off when on your hands and is quite messy. Any idea of what might be causing it and if it is normal or how I can avoid it?

sounds like soot. May be from incomplete combustion of your fuel source.
TBS or billowy white smoke? Charcoal or gas?

That happens to my turkey fryer pot also. Not sure why it happens but yes it is a pain in the a** to clean.

Its gas and the flames from the burner are a kind of billowly lapping type of flames. It's not the type of flame I see in my hot water heater burner.

It sounds like your propane/air mix is off. Flames should be tall blue flames with orange/yellow tips. If you got short blue flames and tall orange tips then too much air is getting into the mixture-make sure that the valve is opened all the way on you bottle then give the valve a quarter turn in the "close" direction. I've checked my GOSM and I didn't see an air control ring anywheres near where the propane enters the burner so you might have to put up with soot. Might be a possibilty that you got some poor quality propane in the bottle.

Scrape it off and send it to me. Makes GREAT willow type stars in mortar shells :{) It's soot, in common, or "lampblack" in other disciplines...and carbon to a chem guy. Acetone will cut it, as will mineral spirits and a couple other things, but acetone evaps quickly and cleanly.

Hey Dutch -
I did find that there is a small screw where the propane enters the burner that allows a collar to turn around an air vent. I am going to play with this a bit and see if I can make any adjustments in the air flow.

Well, the slide piece goes around an area of the tube that is covered with a small mesh screen. Unfortunately, adjusting the slide from completely covering the screened area to not at all covering the screened area does not seem to make any difference in the flame. It always has long yellow lapping flames with just a short bit of blue at the burner.confused.gif

You got a tube there as a feed? Dang spiders and wasps will plugh those up. Run a coathanger wire or something down it if ya can. I found a mudwasp nest in my turkey cooker this spring...damm things anyway.

I use a wet/dry vac in those type of areas to help keep it clean of obstructions.

Not wanting to disassemble anything, I blew out the burner and tube best I could with my air compressor and it certainly seemed to have helped! Now I got the blue flame with yellow tip. Thanks to all for the great help!
