New load of coal..yellow flames???

PostBy: BeerMonley On: Tue Dec 30, 2008 12:12 am

i just put a load of new coal i got today and it started burning yellow flames instead of blue. is this because it was very wet or is there someting mixed in with the coal? ive gottn coal from this place once before but didnt have this happen. it also smelled weird when i first threw it on.

Yellow flames cooler flame.
I get yellow flame from bits of wood when using 'suburban shallow mined' coal.

I've noticed the same thing on similar grade of coal. Eventually goes away and blue ladies come on stage.

Some of mine (ha ha) smells like it was wet down with #2, might account for the yellow flame variation.

i just shook down the first load and the ashes are mostly red, is this normal? did i just get a different quality of coal than i got before or a different kind?

BeerMonley, do a search on "red ash" and "white ash". You'll find a lot of threads dealing with the difference in BTU content, ash content and clinker-ing. I had one load of coal from the same dealer I always uses that burned with a red flame. It wasn't as hot as the coal I usually get from him but it wasn't drastically different.

Have seen that too. With bulk coal,sometimes they add chemicals to prevent the coal from freezing in the hopper cars. When they burn off they can color the flame, or cause that "oily" smell.

When the coal is wet then the small fine pieces stick to the larger pieces. When they dry, the draft pulls them up where they mix with air and burn yellow.
