【摘要】 为准确把握300 MW循环流化床(CFB)锅炉的热力特性,针对目前国内3种典型300MW CFB锅炉炉型,从炉膛、外置床的传热机理和传热计算角度出发,对不同炉型的热力特性进行了分析比较.结果表明:3种炉型CFB锅炉的热力特性均可满足蒸汽参数的要求,且热负荷分配合理.更多还原

【Abstract】 In order to accurately grasp the thermal characteristics of 300 MW Circulating Fluidized Bed(CFB) boilers,analysis and comparison were made for the thermal characteristics of three typical types of 300 MW CFB boiler in China in view of heat transfer mechanism and calculation of furnace and external heat exchanger.Results show that the thermal characteristic of all three types of boiler can meet the requirement of the steam parameters and the heat load distribution is reasonable.更多还原
