循环流化床锅炉近年来在我国中、小电站的建设中应用十分广泛 ,但在风机的选型上存在一些问题。如 :风机的叶型与CFB锅炉的匹配 ;2种叶型风机参数的选择 ;运行工况的调节等。在研究了这些问题和CFB锅炉的燃烧特点后 ,指出循环流化床锅炉中 ,风机应采用后弯式叶轮及变转速调节或入口节流调节的方式。
Circulating fluidized bed boiler in China in recent years, the construction of small power stations is widely used, but there are some problems in the selection of the fan. Such as: fan blades and CFB boiler match; 2 kinds of leaves the choice of fan parameters; operating conditions such as regulation. After studying these problems and the combustion characteristics of CFB boiler, it is pointed out that in circulating fluidized bed boiler, the fan should adopt back-curved impeller and variable-speed regulation or inlet throttling regulation.
