The Selection Of Flue Gas DeNO_x-technology In The Power Plant Of China

The environmental criterion and the emission criterion of the nitrogen-oxide in the state and abroad have been analyzed in the paper. In order to direct the development of the flue gas DeNOX technology in China, the total volume of the nitrogen-oxide and the emission situation on per-kw status of the state with other developed country have been compared.The thesis has pay more attention on introduction of the lower-nitrogen combustion technology and the flue gas DeNOX technology(mainly on technological parameter and economy etc. )In addition , a fuzzy synthetic model has to be made to evaluate the three-main flue gas DeNOX technologies and the result is presented. The combined SO2/NOX removal technologies have to be recommended in the end.
