Abstract: Nitrogen oxides are one of the state total pollutant control objective in the 12th five-year period. The paper summarizes the development of denitrification industry of power plant in China. Based on the discharge status and control regulations of nitrogen oxides from thermal power plant，the current NOx control technology and profiles of domestic and foreign companies are presented，and the industry market characteristics and main existing problems are analyzed. Finally，China’s thermal power plant flue gas denitrification is at a high-speed development period. Denitrification is a huge market and the denitrification catalyst research should be intensified.

Key words: flue gas denitrification, NOx, power plant, market analysis
