[Gasification] [Stoves] Gasifying coal?

[Benjamin Domingo Bof]

Doctor Thomas B. Reed, Crispin en others.
   
  We agree with you. Consortium of solid fuels is very good
  My hobby and job is blacksmith to recycle steel springs making many tools in an sustainable system based in wood energy, logs for houses, beds, chairs and tables.
  When we need higher temperature buy coke from metallurgical stores. 
  For start fire is necessary to ignite pieces of firewood to create proper temperature to burn mineral coal. When is used some forced combustion or convection by chimney higher temperatures are obtained. Then heat transmission is much better. Coal have lesser velocity of combustion.
   This way you can add many times firewood mantaining an coal center where air inlet blows.
  I remeber in Conselheiro Lafaiette, Minas Gerais ,Brazil; an "blade blacksmith" whose nickname was 
  "mentiroso" (lier). He pick up from RR line his coal for make wood knives.
   
   
  Merry Christmas and Happy New Year

  Dear Crispin and All:

In 1998 Robb Walt of CPC asked me the same question: Can the WoodGas 
stove gasify coal. Since coal is only 20% volatile while wood is 80%, I 
didn't think so, but having discovered that my opinions are often wrong, 
I got a few chunks of Western Coal from Coors. (There are long supply 
trains here in Golden, and sometimes pieces fall off - or are helped 
off. It takes a LOT of coal to make beer.) 

I crushed the coal and pea sized it, put it in the stove, ignited it 
with chips/sawdust pellets/coal. (Coal is hard to ignite) and was 
delighted to find that it burned longer even than wood pellets, being so 
dense. It yielded about 50% of "stove coke". Experiment trumps 
opinion again! (Some of my best inventions have come from ignoring my 
instincts.)

The charcoal from our woodgas stove can be a useful byproduct. Any 
suggestions for the "stovecoke"?

Yours truly,

Tom Reed
