Abstract The basic performance of Y pulverized coal was analyzed，and the feasibility of injection in Shougang blast furnace was evaluated at the same time．Compared with the coal which used in Shougang blast furnace presently，the ash content and grindability of Y coal are in the same level，and the calorific value，theoretical replacement ratio，sulfur content and combustibility are higher，and volatilization is lower．The analytical results can be concluded that the fuel ratio would be reduced if Y coal is used in Shougang blast furnace．The industry test was carried out in one blast furnace of Shougang ironmaking plant in September，2009．The highest injected proportion of Y coal was 35%．During test period the blast furnace was in good condition，the corrected replacement ratio of coal increased from 0.80 to 0.83 and coal utilization reached higher than 99%，which brought good economic benefits．
