摘要
中国从"十一五"期间全面启动燃煤电厂二氧化硫减排工作,烟气脱硫设施建设、运行、管理对燃煤电厂的影响很大。通过回顾中国燃煤电厂二氧化硫污染控制工程历程,从政策、法规、标准、技术、设备加装、提效改造、运行、排放量控制等多个方面进行总结和分析,提出了总量计算方法、脱硫作为主设备管理、重视硫资源综合利用等方面的建议。分析表明:燃煤电厂二氧化硫污染控制工作已取得了长足的进步,总量减排成绩突出,但超低排放环保效益偏低,应用的一批新技术还需加强总结。下一阶段应加强系统性研究、重视浓度的控制等方面工作。
The construction, operation and management of flue gas desulphurization facilities have great influences on coal-fired power plants and China started working on the sulfur dioxide emission reduction in coal-fired power plants in a large scale during the 1 lth Five-Year period. This paper reviews the history of the sulfur dioxide pollution control in coal-fired power plants, makes the summary and analysis from the aspects of policies, regulations, standards, technologies, equipment installation and operation, efficiency improvement as well as emissions control, and puts forward suggestions on total amount calculation method, desulfurization equipment management and comprehensive utilization of sulfur resources. The analysis shows that considerable progress has been made in the control of sulfur dioxide pollution in coal-fired power plants and remarkable results have been achieved on the total emission reduction, but the environmental benefit from the ultra low emission is still low and the new technologies need more improvement. The focus in the next phase should be on the systematic research and the sulfur dioxide concentration control.
