Abstract：This paper studies two reburning power generation projects with 10 MW/20 MW gas power in a company based on 660 MW supercritical coal-fired unit boilers with biomass gas induced in. The optimized burner modification scheme is selected combined with the specific features of ‘four corners cutting circular’ and ‘front and back wall hedging’ boilers. According to the specific gas intake method, we comprehensively analyze the NOx emission, main parameters change, low load stable combustion, heating surface corrosion and furnace slag, etc. Also, the performance accounting and computational fluid dynamics (CFD) numerical simulation calculation are carried out in the commissioned boiler factory before and after mixed burning. The NOx decreases obviously, the exhaust temperature increases, and the calculation efficiency of the boiler decreases after burning gas intake in various working conditions.
