efficient than burning firewood

y Moisture content of a briquette can be as

low as 4%, whereas green firewood may

be as high as 65%

ingredients and several minor ones.

y The primary ingredients are char and coal

y The minor material such as binding agent,

an accelerant, and an ash-whitening agent.
