Abstract
The utility model discloses a biomass power generating system. The biomass power generating system is characterized by comprising a gasifying system consisting of a charge pipe, a hearth, a cyclone separator and a return feeder; the rear part of the cyclone separator is sequentially provided with a cyclone deduster, a cooling device, a draught fan, a pulverized coal boiler and a steam turbine; fuel gas generated by the gasifying system is dedusted by the cyclone deduster and cooled by the cooling device sequentially, then is conveyed into the pulverized coal boiler by the draught fan, and is co-fired with pulverized coal so as to produce high-temperature high-pressure steam; steam generated by the pulverized coal boiler does work in the steam turbine so as to generate electricity energy; the fuel gas entering the pulverized coal boiler is low in biomass ash content, and the problem that alkaline metal corrodes the heating surface of the boiler cannot happen. The biomass power generating system disclosed by the utility model has the advantages of high efficiency, no alkaline metal corrosion, no oil tar pollution, running stability and the like.
Description
Technical field
The utility model relates to biomass generation field, particularly a kind of biomass power generation system.
Background technology
Biomass energy is the important energy source that the mankind depend on for existence always, in whole energy resource system, occupies an important position, and it is to be only second to coal, oil and natural gas and the 4th of occuping world energy sources total quantity consumed.According to International Energy Agency statistics, on the earth, coal, oil and natural gas can be respectively about 240,35 and 50 years for the time limit of mankind's exploitation.The fossil energies such as one side coal, oil and natural gas exhaust day by day, and power supply is nervous; On the other hand, the excessive use of fossil energy has caused day by day serious environmental problem.Therefore, develop and find new substitute energy and become the key subjects that human social must be solved in the new millennium.
Conventional biomass generation is mainly biomass direct combustion power generation and Biomass Gasification & Power Generation, biomass direct combustion power generation generating efficiency is 20～25%, efficiency far away from coal dust power plant 40～45%, and biomass direct combustion power generation exists the problem of basic metal corrosion boiler surface, make biomass direct-fired power plant maintenance load when operation.Biomass Gasification & Power Generation is mostly small power generation system, and its efficiency only has 18% left and right, and generating is produced and often to be had the problems such as sewage pollution, generator operation be unstable.
