Bamboo charcoal, which is a kind of fuel charcoal with a broad market prospect, is an excellent fuel
for industrial and domestic use. Bamboo charcoal has a potential to be cleaner and more environment
friendly than coal because of its extremely low content of sulphur and nitrogen. Using bamboo charcoal
as the substitute of traditional charcoal is a feasible way to protect timber resources. The reliability
