A 'SHENZHOUSHENGLONG' coal modifier mainly consists of a grinding aid, a catalyst, an oxidant, a smoke suppressor and combustion improver, a smoke suppressor and igniter, a sulfur fixation agent, a bulking agent, a penetrating agent, etc. The coal modifier is a powdery material and can be added into coal (at a ratio of 0.1% the actual coal weight) to improve the combustion temperature and the combustion speed of the coal, thus achieving catalytic combustion and improving the coal combustion effect as well as the coal utilization rate. Accordingly, the invention performs the functions of saving coal, substituting high-quality coal by poor-quality coal, improving the hourly output of cement clinker stage, improving the grade of cement clinker, fixing sulfur and reducing the discharge of harmful gases such as SO2 in the smoke, thus protecting environment and indeed achieving the green production of cement.
