摘要

针对目前火力发电厂锅炉风机在设计选型时参数裕量选取较大

运行时风门开度较小(对入口调节器调节)或低转速运行(调速运行方式)

风机效率较低的状况

通过对某电厂送风机改造实例的分析

提出了在风机参数选择中的裕量选取需要注意的因素及相关对策

对电厂的节能增效有一定的积极作用。

Abstract

Directing against state of affairs at present

such as margin of typeselection parameters being selected comparatively large during design stage of air fans for boilers in thermal power plants

the opening degree of air fans in operation being often smaller (for adjustment of inlet regulator) or operation at lower revolution speed (for speedregulating operation mode)

and efficiency of air fans being lower etc.

factors and corresponding measures having to pay attention in margin selection of air fan’s parameters have been put forward through analysing practical example of retrofitting forced draft fans in one power plant

playing certain positive role for energysaving and benefitincreasing in power plants.
