The annual output of crops and straws in China is about 6 hundred million tons, and about 3 hundred million tons of the crops and straws can be used as fuel except for part of the crops and straws used as paper making raw materials and livestock feed, which is reduced to about 1.5 hundred million tons of standard coal. The annual available quantity of forest branches and forestry wastes is about 9 hundred million tons, about 3 hundred million tons can be used as energy, and the quantity is reduced to about 2 hundred million tons of standard coal. The planting area of the energy crops such as sweet sorghum, jatropha curcas, pistacia chinensis, tung oil tree and the like can reach more than 2000 million hectares, and the raw material requirement of the biological liquid fuel with annual output of about 5000 million tons can be met.
Biomass power generation is power generation by using biomass energy of biomass, and is one of renewable energy power generation, including power generation by direct combustion of agricultural and forestry waste, power generation by gasification of agricultural and forestry waste, power generation by incineration of garbage, power generation by landfill gas, and power generation by biogas. Biomass boilers use renewable energy sources to produce electricity. Flue gas recirculation refers to a process in which part of flue gas generated by combustion is mixed with an oxidant and then participates in combustion again. The flue gas generated by biomass combustion is difficult to meet the requirements, and the content of nitrogen oxides needs to be reduced by using a flue gas recirculation mode.
