燃煤锅炉烟气SCR脱硝工艺关键技术研究

Study on SCR Key Technology of DeNO_x from Coal-fired Boiler Flue Gas

针对燃煤锅炉烟气中氮氧化物去除技术,主要探讨了选择性催化还原脱硝工艺的关键技术。对不同锅炉燃烧方式、不同烟气参数下选择性催化还原技术中烟气混合技术和催化剂技术对工程设计、运行、烟气脱硝率、氨逃逸及SO2/SO3氧化率等参数影响进行了阐述。

For coal-fired boiler flue gas in the oxides of nitrogen removal technology,this paper focused on the selective catalytic reduction of NOx (SCR) technology in key technologies. It describes the SCR impact of the flue gas hybrid technology and catalyst technology to engineering design, operational、deNOx rates, the escape of NH3 and SO2/SO3 oxidation rate esc in boiler combustion of different ways and smoke parameters.
