FUSION PREVETING AGENT FOR CIRCILATION FLUIDIZED BED BOILER USING SOLID REFUSED FUEL

摘要

The present invention relates to an agent for preventing fusion of a fluidized bed boiler using solid fuel, and more particularly, a fluidized bed boiler that prevents the fusion phenomenon of a fluidized bed boiler by using bottom ash discharged from a pulverized coal boiler such as a coal-fired power plant, which is insufficiently utilized. It relates to an anti-fusion agent. The anti-fusion agent of a fluidized bed boiler using solid fuel according to the present invention includes a pulverized coal boiler bottom ash having a CaO content of 0.1 to 10% by weight and an SO ₃ content of 0.01 to 5% by weight.
