摘要: 为了解决山西焦煤沙曲瓦斯发电厂二期工程存在的通风、冷却、爆震等问题,分析了现状厂房通风形式、冷却机组布置缺陷,从改善主厂房通风方式、优化冷却机组布置、提高冷却机组自身冷却能力等方面进行优化,使得厂房通风方式由原先的发动机侧自然进风屋顶强制排风变为两侧强制进风屋顶自然排风,主厂房夏季环境温度可保持在38℃以下,闭式冷却水箱能够获得新鲜冷空气进行冷却,缸套水冷却能力由836kW提升至1007kW。经改造后,厂房通风效果及机组冷却系统性能得到大幅提升,机组运行负荷率长期稳定在90%以上,爆震现象在一定程度上得到控制。

Abstract: Sha qu gas power plant Project Ⅱ was officially put into operation in 2012, a number of field researches indicated that the project was unreasonable in plant ventilation and cooling water tank layout, which resulting that the unit output was far from reaching the design index requirements of 2MW, the comprehensive utilization of gas was insufficient, the technical and economic indicators were lower than expected. According to the project characteristics and field researches, this paper emphatically analyzes the main causes of insufficient output of gas generator unit, and provides targeted and feasible rectification measures, so as to provide reference for the later rectification of the project.
