摘要
为确定生物质能发电环境方面的可行性,分析了生物质能发电的工艺流程,相比于火电的优缺点,并进行了生物质能热电联厂的大气环境影响评价研究。结果表明:预测评价的烟尘、SO2和NO2排放浓度分别为11.63mg/m3、200.3mg/m3和378.7mg/m3,均远低于火力发电的排放值;在不同条件下、不同地点SO2和NO2的1小时、日均浓度也均远低于火力发电的浓度值。说明了生物质能发电在环境友好性方面具有明显的优势。
To assess the environmental feasibility, the technical process of biomass-fired cogeneration plant as well as its advantages and disadvantages compared with coal power plant were analyzed. Assessment of effect of biomass-fired generation on atmosphere was conducted. The results predicted that the emission concentrations of soot, SO2 and NO2 would be 11.63mg/m^3, 200. 3mg/m^3 and 378. 7mg/m^3 respectively, which were all far below that of coal power plant. The daily and hourly average concentrations of SO2 and NO2 at different conditions and at different locations were also much lower than that of coal power plant. It shows that biomass-fired power plant has an obvious advantage in environmental friendship.
