摘　　要：介绍了中低温脱硝和循环流化床半干法脱硫的工艺原理及特点。河北中煤旭阳能源有限公司焦炉烟气的SO2浓度200~300mg/m3,颗粒物≤30mg/m3,NOx 800~900mg/m3。为了达到地区的要求,采取了中低温SCR脱硝+余热锅炉+循环流化床半干法脱硫工艺,外排烟气SO2≤10mg/m3,颗粒物≤5mg/m3,NOx≤30mg/m3,远低于特别排放限值要求。The process principle and characteristics of medium and low temperature denitration and semi-dry desulfurization by circulating fluidized bed were introduced.The concentration of SO2200-300mg/m3,particulate matter≤30mg/m3 and NOx 800~900mg/m3 of the flue gas from the coke oven.In order to meet the requirements of the region,the medium and low temperature SCR denitration+waste heat boiler+circulating fluidized bed semi-dry desulfurization process was adopted.The exhaust flue gas SO2≤10mg/m3,particulate matter≤5mg/m3,NOx≤30mg/m3,far below the special emission limit requirements.
