燃料在燃烧过程中产生高温烟气携带部分固体颗粒与锅炉传热面接触,形成坚硬的烟灰垢,既阻碍传热、降低热效率,又浪费能源,还因烟灰垢中含有酸性物质腐蚀金属材料.因此锅炉要每天进行数次吹灰,但还不能彻底解决,而且吹灰还要耗费相当数量的蒸气,排出大量灰尘,污染环境,锅炉热效率仍是随着使用时间而下降,运行2—3个月,不得不停炉进行清除. 为了节约燃料,提高锅炉热效率,我们使用化学清灰剂清除锅炉传热面上烟灰垢. 一、化学清灰剂的作用及效果把以硝酸钾为主的化学药剂喷入炉膛,立即被燃烧成白色烟雾与烟灰垢接触,发生化学
Fuel in the combustion process produces high-temperature flue gas to carry part of the solid particles in contact with the boiler heat transfer surface, the formation of a solid soot, not only impede heat transfer, reduce thermal efficiency, but also a waste of energy, but also due to the soot contains acid corrosion of metal materials. Therefore, the boiler to blow several times a day ash, but can not be completely solved, and soot also consume a considerable amount of steam, emit large amounts of dust, pollute the environment, the boiler thermal efficiency is still down with the use of time, running 2-3 Month, had to stop the furnace for removal.In order to save fuel and improve the boiler thermal efficiency, we use chemical cleaning agent to remove the ash on the heat transfer surface of the boiler.First, the role of chemical cleaning agent and the effect of potassium nitrate-based chemistry The chemical was sprayed into the furnace and immediately burned into white smoke to come into contact with the soot, causing the chemical to take place
