摘　　要：酸露点是锅炉设计和运行中重要参数之一,目前国内外计算烟气酸露点方法很多,但是不同方法计算结果差异较大。结合有关文献对几种计算烟气酸露点的方法进行了比较,分析了SO_3浓度和水蒸气含量对烟气酸露点变化趋势的影响。研究结果表明,荷兰的A.G.Okkes公式和И.A.Bapahoba公式比较精确,前苏联热力计算酸露点经验公式、日本电力研究所经验公式和Haase & Borgmann公式的误差比较大。此外,对前苏联热力计算酸露点经验公式进行了修正。Acid dew point of flue gas is one of the most important parameters of the design and operation of boiler. At present, there are lots of calculation methods of acid dew point of flue gas, and the results of different methods are quite different. This paper compares several methods in reference to relevant literatures, analyzes the effect trend of SO3 concentration and H2O vapor on acid dew point. The following results are obtained from the study： A.G. Okkes formula and И. A. Bapahob formula are more precise than the others but formula of acid dew point in the thermal calculation from the former U. S. S. R, formula of Japan Electric Power Research Institute and formula of Haase ＆ Borgmann have more error. Finally it corrects the formula of acid dew point in the thermal calculation from the former U. S. S. R.
