摘要
本文论述了由ＣＦＢＣ锅炉炉膛下部密相区内循环燃烧技术与炉膛上部稀相区空间循环燃烧技术所构成的炉内多重内循环燃烧技术的原理与结构．应用本技术所设计完成的循环流化床锅炉，具有效率高、体积小．成本低、磨损轻、动力消耗低、运行稳定、操作方使、负荷调节范围广、煤种适应性强等优点．是工业循环流化床锅炉的理想炉型．长期的运行实践证明，炉内多重内循环燃烧技术是适用于矮小燃烧空间的工业循环流化床锅炉的理想技术之一。
The principle and structure of multiple in-furnace cerculating combustion technology of a CFBC boller comprlsing lnner circtilating combustion technoloby of furnace lower portion dense-phase region and circulating combustion teehology of furnace upper portion rare-phasa region are discussed in the present paper. Tile circulalillg fluidiscd bed boiler. based on the above-cited technology, has the following advantages: high efficiency, small space. low cost. light wear. low power consumption, stable and simple operation and a wide range of load adjustment capability as well as a high adaptability to the burning of various coals. In view of the foregoing it pertains to an ideal type of illdustrial circulating fluidized bed boiler. Its long-term operation has proved that the multiple In-furnace circulating combustion technology is ideally suited for industrial circulating fluidized bed boilers of small and low-height conlbusiion spaal.
