摘要

针对锅炉运行中存在并联运行引风机"抢风"的问题

从风机性能曲线、工作点角度入手对AN型静叶调节轴流引风机进行了分析。结果表明

由于引风机"抢风"

整个管网的阻力曲线发生了变化

使得风机工作点落入∞形区域内

导致炉膛压力处于不稳定状态甚至使风机出现过电流而损坏。根据实例

对引风机"抢风"的现象、原因进行了分析

并提出了防范措施。

Abstract

In operation of boilers

the problem of "scrambing for air" is existing between the axial induced draft(I.D.) fans connected in parallel operation.Regarding to this

starting from the performance curve and the angle of working point for said fans

the problem of "scrambling for air" concerning AN type axial I.D.fans with stationary blade adjustment has been analysed.Results show that the resistance curve of the whole pipeline network has changed due to "scrambling for air"

making the working point of said fans to be dropped into ∞-shaped region

the "scrambling for air" can make pressure in the furnace to be in an unstable state

even making the fans to be damaged due to occurrence of large electric current.Based on the living examples

the phenomenon

cause

and disposal of problem "scrambling for air" of axial I.D.fans have been explained

and some preventive measures being put forward.
