摘要
针对目前火电厂因燃煤严重偏离锅炉的设计煤种导致的锅炉燃烧问题(炉膛压力超限、全炉膛火焰丧失)而引起的锅炉MFT(Master Fuel Trip,主燃料跳闸)日渐增多的情况,提出可通过火电机组停炉不停机功能成功动作的技术,可以避免机组的非停,减少燃油消耗,解决锅炉MFT后恢复时间过长的问题。文章叙述了合山发电有限公司2×330 MW机组成功实施停炉不停机技术的工程实践,并对试验的结果进行了分析,结果表明:停炉不停机控制技术是可行的。
It is now a common problem to thermal power plants that coals are usually deviated from design value of boiler, which lead to boiler＇s combustion problems （such as furnace pressure exceeds limit, loss of all fumace flames） and thus lead to boiler＇s MFT. The technology of boiler shutdown without stopping turbine is proposed to avoid the shutdown of generator set, which reduce fuel consumption and avoid long period of restarting time after boiler＇s MFT. The technology has been practiced at 2 ×330MW generator sets in Heshan power generation Co., Ltd. Test results show that the proposed technology is feasible.
