摘　　要：美国燃煤发电厂发展的总体目标是提高效率、环境友好和降低成本.电厂效率要达到55%～56%;SO 2、NO x 及固体颗粒的排放降低到现有标准的1/10以下,二氧化碳及温室气体排放降低50%以上;发电成本在现有基础上减低10%～20%.为实现这些目标,主要是发展先进的低排放锅炉系统(LEBS)、高性能动力系统(HIPPS)、压力流化床燃烧(PFBC)、整体气化联合循环(IGCC)以及先进的环境控制技术.The US is working to develop highly advanced coal--fired power generation systems that will have significantly higher thermal efficiency, superior environmental performance, and a lower cost of electricity than current coal--fired power plants. The goal is to develop the systems to provide 55%-60% plant thermal efficiency and reduce the emissions of sulfur dioxide, nitrogen oxides, and particulates to the level of less than one tenth of the current Federal standards. Emissions of carbon dioxidE, a greenhouse gas, will also be reduced by up to 50% and the cost of electricity will be 10%-20% lower then the cost of todayrs plant. Advanced systems include low emission boiler systems （LEBS）, high performance power systems （HIPPS）, pressurized fluidized bed combustion （PFBC）, integrated gasification combined cycles （IGCC）. Advanced environmental control technologies. This paper presents these new technologies.
