How to produce rice husk charcoal

Rice husk charcoal is formed by insufficient combustion of rice husk when heated to below its ignition temperature. Rice husk is the outermost part of the rice seed which is a hard layer and a waste material from rice milling. Therefore, the raw materials for producing rice husk charcoal are abundant and low in cost. Making rice husk charcoal is a low-cost and high-yield business. There are two ways of making charcoal from rice husk, one is directly carbonizing it into charcoal through a carbonization furnace, then compressing the rice husk charcoal into briquettes. The other is to compress rice husk into biomass briquettes first, then carbonize the rice husk briquettes into charcoal. Here we will introduce these two rice husk charcoal-making processes separately. [...]
