摘要
为降低锅炉烟气中氮氧化物对环境的污染,以氨为还原剂采取烟气脱硝工艺技术将烟气中的NOX还原为N2,从而使烟气中NOX的排放达到国家标准要求,减少对大气、环境的污染。同时对烟气脱硝的工艺、催化剂和还原剂的选择等进行比较。
In order to reduce the pollution of nitrogen oxides in flue gas of boiler on the environment, taking the process technology of flue gas de - NOx, the NOx in flue gas was reduced to N2, by using ammonia as reducing a- gent, so that the NOx in flue gas emissions was up to the national standard, atmospheric pollution, environment re- duced. At the same time, comparison with the flue gas de - nitration process, catalyst, reducing agents etc. was per- formed.
