摘　　要：烟气酸露点是燃煤电站锅炉设计和运行的重要参数之一,目前国内外计算烟气酸露点方法很多,针对某燃煤电站实际燃用煤种和运行工况,通过典型公式计算分析得出烟气酸露点计算的影响因素,分析现场实测和公式计算结果偏差较大的原因。同时针对计算得到的酸露点温度,对加装低温省煤器的适用性做进一步探讨。Acid dew point of flue gas is one of the important parameters for design and operation of coal-fired power plant boiler, at present, we have many calculation of flue gas dew point method in the domestic and foreign, for a coal-fired power station actual coal types and operating conditions, through the typical formula analysis of factors that influence the calculation of acid dew point of flue gas, analysis of field measurement and calculation results of large deviation reasons. At the same time for the calculation of acid dew point temperature, make further study on the applicability of the installation of low temperature economizer.
