| As China NOx emission standards become stricter day by day, the NOx emissions control and de-NOx of the flue gas by combustion regulation has become the main technical way of abatement in coal fired power plant.This paper reviewed the domestic and overseas development of de-NOx technology,described in detail the the commonly use of nitrogen oxide control technology and its application situation.Compared the advantages and disadvantages of various de-NOx technologies to link up with the requirements of reconstruction denitriflcation of the330MW unit power plant. The current best de-NOx technical solution-Selective Catalytic Reduction (SCR) flue gas denitriflcation process was analysed through comparing the deNOx system investment and operation conditions of the other plants.Our topic aimed to research the achievement of low NOx emissions in the330MW unit of Coal fired power plant, the effect of NOx emission reduction and the impact on combustion stability after the conbustion technological retrofit of the number5coal-fired boilers.Combined the production status, fuel indicator, the site profiles, etc. of the1025t/h coal-fired boiler in Coal fired power plant to choose SCR flue gas denitrification process. Analyse the SCR flue gas denitrification system on the technology. Analyse and evaluate the results of the low NOx combustion and SCR flue gas denitrification retrofit.The rearch work of low NOx combustion technology and SCR flue gas denitrification process can provide a reference for future similar projects in the future. |
