摘要

为适应季节性负荷变化

对某热电厂循环流化床锅炉引风机在非采暖期低负荷下选用低速小功率高压电动机的可行性进行分析。结果表明

在非采暖期将4号炉引风机原配630kW、1000r/min电动机改为335kW、750r/min后

可满足锅炉燃烧要求

此改造投资回收快

经济效益可观。

Abstract

In order to suit the variation of load in different seasons

an analysis of feasibility to retrofit induced draft fan of the CFB boiler in one power plant into a low speed one by using high-voltage small capacity motor during non-heating seasons has been made.It is believed from analysis that the payback period of investment is short

and the economic benefit being significant.After retrofitting the motor of induced draft fan for boiler no.4 into a 335 kW and 750 r/min one

it can satisfy the requirements of combustion in the boiler.
