近年来,随着火电建没项目的增加,火电厂容量的增大及我国环境保护的迫切需要,控制火电厂的烟气污染已成当务之急。限于我国国情,既不能改变燃用含硫份更低的煤种,又无力支付烟气脱硫设施的费用,在电厂设计中只能贯彻“高烟囱排放”的技术 In recent years, with the increase in thermal power projects, the increase in the capacity of thermal power plants and the urgent need for environmental protection in China, the control of smoke pollution in thermal power plants has become a priority. Due to China’s national conditions, it is impossible to change the type of coal with lower sulfur content, and it is unable to pay for the cost of flue gas desulphurization facilities. In the power plant design, only the technology of “high chimney emission” can be implemented.
