摘　　要：将灰粘熔排渣技术与内循环流化床相结合来焚烧生活垃圾,不仅有利于城市生活垃圾中大块不可燃物的排出,同时还能对焚烧灰渣作进一步的减容。因此,在1个内循环流化床燃烧试验台上进行了以煤为燃料的热态试验。结果表明,非均匀布风是实现连续粘熔排渣的必要条件,同时还必须严格控制炉膛密相区的温度。Appling agglomerated ash discharge technology to internally circulating fluidized beds for incineration of municipal solid waste （MSW） is not only advantageous for discharging lumps of non-combustible matter, but is also helpful for reducing the bulk of incineration residues. Therefore, hot state tests were carried out, on an internally circulating fluidized bed test rig, using coal as fuel. Test results indicate that non-uniform air distribution is an indispensable condition for realizing continuous discharge of ash agglomerates; simultaneously, the temperature of the furnace＇s dense phase zone has to be kept under strict control.
