摘要

某锅炉空气预热器烟风侧差压长期偏高

严重影响机组安全运行。为保证机组高负荷长时间运行

在该锅炉上进行了空气预热器在线水冲洗试验。试验结果表明

冲洗效果较好

节约了停机冲洗起停机所需的起动及助燃用油。

Abstract

The pressure difference at flue gas and air side in air preheater of one boiler has been comparatively high in a long term

affecting seriously safe operation of the unit.In order to ensure long term operation under high load of the unit

an on-line water flushing test of the air preheater has been carried out on the said boiler.Results of test show that the effectiveness of water flushing to be better

saving fuel oil needed for start-up and combustion-supporting in the process of start-up and shut-down for water flushing after stoppage of the unit.
