[TheForge] coal "ash" -supplemented wood heat?

[Jerry Frost]

Bruce:

If you're talking about metallurgical coal it's a bad 
idea. If there's enough left to get heat from it'll 
burn right through the stove bottom, even a cast iron 
grate won't last long. This has become a part of local 
lore.

The mountain range you can see due north of us, the 
Talkeetnas, has major coal deposites but not so 
commercially viable to develop. About 40 miles up the 
Glenn Hwy. is Sutton where I used to mine my anthricite 
heater coal. Another 20 or so miles up the Hwy. is 
Chickaloon and Castle Mtn. This mine produced some 
super quality metallurgical coal and the stories about 
people burning themselves out of home and shop are 
legion. There are actually signs hanging near the digs 
warning not to use it for heating.

On the other hand you might be able to make a 
refractory firepot and do it that way but I won't 
recommend it.

We get a lot of partially burned coke and coa, in very 
small pieces,l in what passes through the clinker 
breaker.  We end up throwing it out.  I was wondering 
about the advisability of tossing it into a wood stove 
and maybe getting out the residual BTU's and reducing 
it to possibly a less hazardous ash.

Anyone know anything about doing this?
