4烟气脱硝技术 Flue Gas DeNOx Control Technologies

4.1位于大气污染重点控制区域内的新建、改建、扩建的燃煤发电机组和热电联产机组应配置烟气脱硝设施,并与主机同时设计、施工和投运。非重点控制区域内的新建、改建、扩建的燃煤发电机组和热电联产机组应根据排放标准、总量指标及建设项目环境影响报告书批复要求建设烟气脱硝装置。

4.1 The new, renovate or expanded coal-fired and cogeneration units located in air pollution control “Focus Regions” should be equipped with NOx Control facilities which should be designed, installed and operated at the same time as the boiler. All the new, renovate or expanded coal-fired and cogeneration units “Not in Focus Regions” should comply with the respective permit report approved NOx Emission Standard, total emission target and Environmental Impact Assessment (EIA) requirement.

4.2对在役燃煤机组进行低氮燃烧技术改造后,其氮氧化物排放浓度仍不达标或不满足总量控制要求时,应配置烟气脱硝设施。

4.2 The operating units after installing the Low NOx Technology, if the NOx level still cannot meet the emission standard or total emission reduction requirement should install flue gas deNOx facility.

4.3烟气脱硝技术主要有:选择性催化还原技术(SCR)、选择性非催化还原技术(SNCR)、选择性非催化还原与选择性催化还原联合技术(SNCR-SCR)及其他烟气脱硝技术。

4.3 Major flue gas deNOx technologies include: SCR, SNCR, Combined SNCR-SCR and other deNOx technologies.

4.3.1新建、改建、扩建的燃煤机组,宜选用SCR;小于等于600MW时,也可选用SNCR-SCR。

4.3.1 The Newly, renovated or expanded plant?s coal-fired units should prefer to use SCR. Units equal to or smaller than 600 MW can also choose to use SNCR-SCR.

4.3.2燃用无烟煤或贫煤且投运时间不足20年的在役机组,宜选用SCR或SNCR-SCR。

4.3.2 Operating units burning anthracite or low grade Ping coal and with less than 20 years vintage should prefer to use SCR or SNCR-SCR.

4.3.3燃用烟煤或褐煤且投运时间不足20年的在役机组,宜选用SNCR或其他烟气脱硝技术。

4.3.3 Operating units burning bituminous or brown coal and with less than 20 years vintage should prefer to use SNCR or other flue gas deNOx technologies.

4.4烟气脱硝还原剂的选择

4.4 Selection of Reducing Agent for flue gas DeNOx Process

4.4.1还原剂的选择应综合考虑安全、环保、经济等多方面因素。

4.4.1 The selection of reducing agent should consider overall factors including safety, environmental protection, economics, etc.

4.4.2选用液氨作为还原剂时,应符合《重大危险源辨识》(GB18218)及《建筑设计防火规范》(GB50016)中的有关规定。

4.4.2 When choosing anhydrous ammonia, the unit should meet the regulations stipulated in 《Identification of Significantly Large Hazardous Sources《GB 18218》 and “Fire Prevention Specifications in Architect Design《GB50016》”.
