美国燃煤电厂环保发展历程

Environmental protection roadmap for coal-fired power plants in the US

通过对美国燃煤电厂环保政策法规、污染物控制技术和成效的介绍展示了美国燃煤电厂对控制污染物排放,促进空气质量改善所做的贡献。美国的燃煤电厂在一系列环保政策的相互作用下,通过采取相应的减排技术,已经显著的降低了火电厂SO_2和NO_x等污染物的排放。同时,由于天然气等清洁能源的价格优势及对碳排放的政策要求,美国的能源结构正在由煤炭向清洁能源转变。

By introducing the environmental protection laws and regulations, pollution control technologies and a- chievements in US coal- fired power plants, the article revealed the power plants＇contribution in reducing pollu- tants emissions, and promoting air quality improvement in the United States. The coal - fired power plants in the US has significantly reduced S02 and NO, emissions due to the interaction between environmental policies and emission control technologies. Meanwhile, due to the price advantage of natural gas as well as the carbon re- duction policy trend, the US power sector is going through a transition to clean energy.
