摘要

Three dimensional model of 350 MW utility boiler furnace was established by CFD to explore the combustion characteristics of pulverized coal at different O_2/CO_2 ratios. The temperature field, sub-concentrations distributions, burner wall heat loads and movement trajectories of pulverized coal particles were analyzed and compared with those in the air atmosphere. The numerical results shows: the furnace temperature increases as the value of O_2 concentration and the peak value of radiation appears at 20 metres in furnace; Oxygen enrichment combustion process can effectively reduce the exhaust flue gas temperature;The combustion condition with 30 % oxygen concentration is the closest to air combustion.
