国产锅炉机组运行中,排烟温度普遍高于设计值。排烟温度升高,排烟损失增大,从而导致锅炉效率降低,煤耗升高,经济效益下降,本文通过理论分析,并结合现场经验,对引起排烟温度升高的原因从运行调整的角度进行了分析、归纳,针对不同的起因,提出了相应的措施和建议。 Domestic boiler unit operation, the exhaust temperature is generally higher than the design value. Due to the increase of exhaust gas temperature and the increase of smoke exhaust loss, boiler efficiency is reduced, coal consumption is increased, and economic benefits are reduced. In this paper, theoretical analysis and field experience are used to analyze the causes of exhaust gas temperature rise from the perspective of operation adjustment Analyzed, summarized, for different causes, put forward the corresponding measures and suggestions.
