电站锅炉省煤器磨损泄漏研究

Research on Economizer Leakage and Abrasion

针对朔州能源发展有限责任公司自备电站2号炉省煤器频繁磨损泄漏这一现象,进行专题分析、研究,采用新技术,对2号炉省煤器进行了技术改造,在保证吸热量及锅炉效率的情况下,降低烟气流速,有效解决了省煤器的磨损问题,保证了机组长周期无泄漏运行,经济效益明显,达到预期效果。

According to the phenomenon of economizer leakage and abrasion of No. 2 boiler in Shuozhou Energy Develop ment Company, analysis, research and new technique are proposed. In the circumstances of good thermal absorption and boiler efficiency, the technique improvement of No. 2 economizer decreases stack gas and its abrasion, which ensures the ma- chine operation with long period and no leakage.
