摘　　要：随着国家对生态环境保护工作重视程度不断提高,国内大中型燃煤电厂均完成了超低排放改造,京津冀区域燃煤电厂按烟气深度治理要求完成烟气深度治理改造,烟气污染物排放浓度限值已领先于国际水平。烟气超低排放必然带来相应生产维护成本的增加,尤其现在燃煤电厂受煤炭市场影响,景气指数下降,面临综合运行成本不断增加的压力,如何实现降本提效成为燃煤电厂面临的共同难题。本研究以某燃煤电厂为例,概述其为保持环保设施可持续性健康发展,降低运营成本,达到环保与经济两者的有效平衡,深入开展石灰石-石膏湿法脱硫系统经济运行实践,脱硫系统单位成本下降明显,摸索出一套适用于大中型燃煤电厂的脱硫系统经济运行实践方向,效果显著。With the increasing emphasis on ecological environment protection by the country,large and medium-sized coal-fired power plants in China have completed ultra-low emission transformation.Coal fired power plants in the Beijing-Tianjin-Hebei region have completed deep flue gas treatment transformation in accordance with the requirements of deep flue gas treatment and the emission concentration limits of flue gas pollutants have exceeded the international level.The ultra-low emission of flue gas will inevitably lead to an increase in production and maintenance costs,especially now that coal-fired power plants are affected by the coal market,the economic index is declining,and they are facing the pressure of continuously increasing comprehensive operating costs.How to achieve cost reduction and efficiency improvement has become a common challenge faced by coal-fired power plants.This study takes a certain coal-fired power plant as an example to summarize its efforts to maintain sustainable and healthy development of environmental protection facilities,reduce operating costs,and achieve an effective balance between environmental protection and economy.It deeply carries out energy-saving and consumption reducing practices of limestone gypsum wet desulfurization system.The unit cost of desulphurization system decreased obviously.A set of energy-saving and consumption reducing practices suitable for large and medium-sized coal-fired power plants has been explored,and the effect is significant.
