摘　　要：针对GB 10184—88《电站锅炉性能试验规程》和GB/T 10184—2015中空气预热器漏风率计算方法进行分析,数据结果表明两种版本计算的漏风率相对偏差在3%左右。考虑到旧版标准的局限性和新版标准的试验复杂性,提出一种混合两种标准的计算方法,漏风率介于新旧标准之间,同时能相应降低计算工作量。In the article,two calculation methods of air preheater air leakage rate in GB 10184—88 Power Station Boiler Performance Test Regulations and GB/T 10184—2015 are discussed.The data results show that the relative deviation rate of the air leakage calculated by the two methods is about 3%.Taking into account the limitations of the old method of the standard and the test complexity of the new one,an improved calculation method that mixes the two standards is proposed.After the improvement,the air leakage rate is between the old and the new standard,and the calculation workload can be reduced accordingly.
