摘要

总结了现有的几种生物质发电方式,并提出了生物质沼气化与燃煤联合循环发电的利用方式。采用联合发电方式,沼气发电容量可以根据电厂周围生物质资源的多少灵活选择,同时沼渣可以作为有机肥就地销售给当地农民。与纯燃生物质发电相比,该种发电方式效率较高;与混燃生物质发电相比,该种方式可以享受国家高额的电价补贴。因此,该种方式是综合优势较为明显的一种发电方式,同时,生物质发酵所产生的沼气还可以替代电厂的点火与助燃用油,进一步提高电厂的经济效益。

Abstract

Several existing modes of biomass power generation were summarized, and the method of combined cycle power generation of methane and coal was proposed. With this kind of power generation, the capacity choose of methane power generation can be flexibility according to the biomass resources around the plant, and the methane residue can be sold to local farmers as organic fertilizer. The combined cycle power generation has higher power generation efficiency compared with the pure biomass combustion power generation, and can obtain national high electrical price subsidies compared with co-firing power generation. So the combined cycle power generation has more obvious comprehensive advantages. Meanwhile, the methane produced in the fermentation of biomass can replace the oil consumption of ignition and combustion supporting, which can further improve the economic benefits of plant.
