Power generation by using biomass gas from rice husk, wood chips saw dust and crop stalks can not only save expenditures in electricity tariff in the production cost of rice mills and timber processing mills, but also can bring about benefits by means of selling surplus electric power to the power grid. As the higher conversion efficiency of the equipment by taking rice husk as an example, every kwh power generation consumes only 1.6~1.8kg of rice husk. if using wood dust or crop stalks as fuel, the unit consumption of the fuel will be still lower.
