【摘要】 利用生物质代替矿物燃料发电可以减少CO2和SO2的排放量。确定了燃煤机组CO2和SO2排放量基准,建立生物质发电的CO2和SO2的排放量模型及其偏差模型;计算不同发电方式下CO2和SO2的生成量及减排量;分析了气化炉气化效率对生物质发电CO2和SO2生成量的影响。结果表明,提高生物质发电效率和气化效率可以显著降低CO2和SO2的排放;生物质发电的环境效益明显优于燃煤发电,而生物质气化合成气与煤混燃发电的环境效益优于生物质直燃发电。更多还原

【Abstract】 Power generation by biomass instead of fossil fuel can reduce emissions of CO2 and SO2.The emission baselines of CO2 and SO2 of coal-fired units were determined and the emission models and the deviation models of CO2 and SO2 were established;the production and emission reduction of CO2 and SO2 under different power generation modes were calculated;the impacts of gasification efficiency to production of CO2 and SO2 were analyzed.The environment benefit of biomass power generation is better than that of coal-fired power generation and the environment benefit of combining biomass gasification and coal combustion is better than that of biomass combustion.更多还原
