中文摘要	针对3台CFB锅炉的热力匹配,研究了300 MW亚临界CFB锅炉两种不同受热面布置方式下工质侧与烟气侧的热力匹配以及350 MW超临界CFB锅炉的热力匹配,定量的分析了蒸汽参数的变化对于锅炉各级受热面吸热分配的影响规律。对于超临界350 MW CFB锅炉,加热吸热的比例在21%左右,过热吸热的比例在61%左右,再热吸热的比例在18%左右;研究表明,蒸汽参数的变化对锅炉各级受热面之间的吸热分配有很大的影响,合理布置这些受热面是锅炉容量放大的关键。; In the light of the thermal matching of three boilers,studied were the thermal matching of the working medium side and the flue gas side of a 300 MWe subcritical CFB boiler in two different heating surface arrangement modes and that of a 350 MWe supercritical CFB boiler and quantitatively analyzed was the law governing the influence of changes in the steam parameters on the distribution of heat absorbed by various heating surfaces at various levels of the boilers. For a 350 MW CFB boiler,the proportion of heat absorbed during the evaporation process of feedwater is around 21%,that during the superheating process about 61% and that during the reheating process approximately 18%. It has been found that changes in steam parameters have a very big influence on the distribution of heat absorbed by various heating surfaces at various levels,thus proper arrangement of these heating surfaces becomes thekey to the capacity expansion of the boiler.
