The gas-injection BF process was proposed in order to overcome the adverse effects of pulverized coal injection,where the reducing gas produced by normal coal in a gasifier is injected to BF from tuyeres.The influence of process parameters on gas quality was determined. The results show that CO+H2 content and calorific value of gas first increases and then decreases with gasification agent flow increasing,while steadily increases as the reaction temperature,material thickness,oxygen enrichment rate increase.When gasifying agent flow rate is 1.0 m3/h,the reaction temperature is 1 000 ℃,the material layer thickness is 1 000 mm,oxygen enrichment rate is 15%,the best gas quality can be achieved where CO + H2 content reaches at 79.37% and LHV of gas reaches at 10 229.51 kJ/m3.
