摘    要:未来5年(2006~2010年)上海进行脱硫的机组将达957.2万kW,文章对上海市未来5年中脱硫副产物的资源化利用,进行了技术、经济分析,预计每年可节省SO2排污费用约1.02、1.28亿元,如以原煤计,则为1.51亿元/a和1.89亿元/a,到2010年将达1.67~2.09亿元/a,折成原煤则为2.34~2.93亿元/a,如排污费提高,效益还将扩大;电厂脱硫石膏销售将获得约2160~2880万元/a,折算成原煤应为3024万元/a和4032万元/a,如加工成球或利用余热烘干成粉,利润还会增加;到2010年脱硫石膏销售收入还将进一步放大。上海石膏板或水泥企业利用54~72万t的脱硫石膏,可使企业的原料购买成本节约3250~3650万元/a,如将FGD石膏40%SO3含量与天然石膏34%相比算入成本,使用FGD石膏的水泥生产企业原料购置费节约将更显著。

关 键 词:电厂  烟气脱硫(FGD)  副产物  石膏  水泥  资源化  可行性分析

Abstract:Based on the analysis of third three-year environment protection action plan and 11th five-year plan of Shanghai,the utilization of by-product of flue gas desulfurization(FGD) as resource material as well as environmental,economic and health benefit from SO2 emission reduction on condition of 6.508~9.572 million kilowatts generating units in power plants were estimated for the next five years.Technical and economic analysis on utilization of FGD-gypsum as resource materials were made,and results showed that FGD-gypsum has better quality than natural gypsum and it is completely feasible to replace the latter in the production.It was concluded that FGD gypsum as resource material will generate positive effect on environment,economy and health,and application of FGD and its by-product to power stations was also proposed.
Keywords:power plant  flue gas desulfurization(FGD)  by-product  gypsum  cement  resourcilization  feasibility analysis
