摘　　要：广东粤华发电有限责任公司#5锅炉A级检修后,出现了两侧排烟温度偏差过大的问题,不利于锅炉风烟系统运行调整,给机组的安全、经济运行带来一定的影响。分析了两侧排烟温度发生偏差大的原因,提出了处理措施,其经验可为遇到类似问题的同类型电厂提供借鉴。After Class A overhaul of No.5 boiler in company, the flue gas temperature deviations are too large on both sides, which is not conducive to the adjustment of the boiler air and gas system operation, and it has a certain impact on the safety and economic operation of the unit. The reasons for the large deviations in flue gas temperature have proposed treatment measures, and its experience can provide integration for the same type of power plants with similar problems.
