Technical analysis and application of wide-load-range denitration retrofit for large coal-fired power generation unit boilers with hot water recirculation
By quantitatively analyzing the constraints on low-load operation of the 680 MW ultra-supercritical coal-fired power plant unit of Huaneng,a technical plan for wide-load-range denitration retrofit combining boiler feedwater recirculation and economizer feedwater bypass is proposed.The results show that the scheme has a small amount of transformation,low investment,short construction period,small operation amount and low maintenance cost of the new equipment,which solves the safety and performance problems of the denitrification device with the minimum technical output,and does not affect the economic performance within the normal operation load range,and has certain promotion value.
