Fan fed TLUD designed for rice husk. They are very popular and are sold in large numbers without subsidy. Works great as an automatic rice cooker with 3 cups husk for 1 cup rice. A fan delivers a small amount of air to the bottom of a biomass cylinder and a large amount of oxygen at the top of the cylinder. This heating of the biomass in a low oxygen environment results in the production of charcoal (biochar) and a large amount of smoke. This smoke is then burnt in the plate of fire which occurs when the gas released from the heated biomass meets the additional oxygen supplied at the top of the stove.
