水煤浆在垃圾焚烧炉中的应用

Application of coal water mixture in the process of garbage cineration in incinerator

为探索水煤浆在垃圾焚烧炉内燃烧的稳定性与经济性,弥补垃圾热值不足,提高垃圾焚烧的稳定性和发电量,采用合适的浆液输送和雾化设备,对南海环保电厂垃圾焚烧炉进行了水煤浆代油助燃垃圾焚烧的改造。在原垃圾焚烧炉的炉膛和二次燃烧室分别布置两台水煤浆燃烧器,运用合理的设计与操作程序,使水煤浆与压缩空气的压力合理匹配,实现了水煤浆在波动的焚烧炉内稳定雾化、燃烧。水煤浆代油助燃的调试运行表明,在南海环保电厂用水煤浆代油助燃焚烧垃圾,利用烟气余热发电,可以达到垃圾焚烧炉运行稳定、提高垃圾余热发电量的目的。

To stabilize the combustion of coal water mixture in garbage incinerator and improve combustion efficiency,adopt appropriate slurry transportation and atomizing unit to transform the garbage incinerator of Nanhai Environmental Protection Power Plant.Replace the oil with coal water slurry which support the combustion of garbage.Arrange respectively two sets of CWM burners at the furnace and the secondary combustion chamber of the original garbage incinerator.Through rational design and operation procedure,make the coal water mixture content match the pressure of compressed air,this method can stabilize the combustion and atomization of coal water mixture in incinerator,meanwhile the heat of waste gas can be used to generate power.
