摘要：
To research the influence of different pulverized coal injection ways on combustion efficiency, coal tar replacement ratio and economic benefit in blast furnace, the mathematical model of pulverized coal combustion process in the raceway was established based on the No.3 blast furnace in an iron and steel company. The influences of different types of coal, spray gun and oxygen enrichment rate on pulverized coal burnout were studied based on this mathematical model. The results show that the burnout of bituminous coal and double coal spray gun are the highest in different types of coal and spray gun, and the best oxygen enrichment rate is 5% when the coal injection rate is less than 150 kg/t.
