| Abstract: | The technology principle of composite staging low NOx combustion and the low NO~ combustion retrofit seheme of 600 MR pulverized coal boiler is introduced. Combined with selective catalytic reduction （SCR） teehniqae for title gas denitration, the eco. nomical analysis of low NOx combustion technology is carried out. The analysis results show that in appropriate range of NOx reduction. without reducing the boiler combustion efficiency, the initial investment and operation cost using the low NO, combustion technology it much lower than by using SCR technology. |
