China's rural energy consumption of 50% from biomass energy, and which is mainly firewood, straw, direct combustion, the total amount of more than 200 million tons per year. In order to improve energy utilization, one is to promote advanced fuel-efficient stove, thermal efficiency can be increased to 30%; the second is to promote advanced rural biogas technology, straw as biogas fermentation raw materials, both high-quality gaseous fuels, but also make high-quality methane residue fertilizer returned to the field, a two-in-one approach, which is an important way to solve the problem of rural energy.
