Fluxing agent for improving coal ash fusibility and addition method of fluxing agent

The invention relates to a fluxing agent for improving coal ash fusibility and an addition method of the fluxing agent, belonging to the technical field of improving the coal ash fusibility. The method can be used for solving the problem that a current method for improving the coal ash fusibility brings passivity to production, the fluxing agent comprises limestone and iron ore, the addition amount of the limestone accounts for 2.5-4% of the mass of raw coal, and the addition amount of the iron ore accounts for 2-3.5% of the mass of the raw coal. The addition position is selected to be in front of a coal mill, a belt is adopted to weigh and feed materials or a disk feeder is adopted for feeding materials. The fluxing agent effectively improves the coal ash fusibility, not only can guarantee the requirement on mixing uniformity but also can meet the requirement on environmental protection and stable production. 种改善煤灰熔融性的助熔剂及其添加方法，属于改善煤灰熔融性的技术领域，可解决现有改善煤灰熔融性的方法对生产带来被动的问题，助熔剂包括石灰石和铁矿石，石灰石的添加量为占原煤质量的2.5%~4%，铁矿石的添
