Nice Ash!

PostBy: thornhurstian On: Sun Dec 05, 2010 12:31 pm

I'd like to hear what good ash looks like? My rice coal ash comes out of the pan with a high percent of black kernels that look like--well, rice coal (or gravel). I have the requisite 1-2 inches of ash on the end of the stoker grate before it falls into the pan but is this a normal appearance or indicative of something I need to adjust (like coal vendor etc.?).

Do a search on ASH and UNBURNT Coals (there are pics on here). You will have SOME unburnt coals and stuff that doesn't burn (Rocks, etc...) sometimes they ride along the sides, and never get burnt.

Yours should should look either greyish or reddish in color (Depending on the coal company), and sometimes clumpy (coal cakes) depending on how hot your are burning it.

red ash or white ash

If you have a CoalTrol, what are you settings, MIN/MAX , etc...Baro Damper Calibrated correctly ?

The 1-2" of ash is correct at full burn, you can bump the MAX up so you have approx. 1" of ash without pushing hot coals off. Every stove is different, so the MAX for one person, is not the same for another, even with the same stove, because of mechanical and tolerance differences.

But sounds like it's working correctly.
