300MW CFB锅炉一次风机选型原则探讨
摘要
多台已经投运的大型CFB机组出现了一次风机运行工况点远离经济工况的问题
对此通过对两种CFB锅炉的炉型结构和煤质特性的分析
得出了一次风机选型裕量应随炉型结构及煤质特性变化的规律
对大型CFB锅炉一次风机设计选型具有一定意义。
Abstract
The operating point of primary air fans for many large-capacity CFB boilers having already been put into operation is far from the economic operating point.For this
through analysis of boiler structure for two kinds of CFB boilers
and analysis of characters for coal quality
a regularity of type selection for primary air fans has been obtained
i.e.the abundance of type selection should be changed along with boiler structure and coal quality characters
boasting important significance for design and type selection of primary air fans for large-capacity CFB boielrs.
