摘　　要：针对锅炉漏风常规测试方法测点分散、测量误差不易控制等问题,提出利用空气预热器热平衡原理测试锅炉炉膛漏风的新方法。该方法不需要对炉膛负压进行多工况下的调整,是现场人员测试炉膛漏风、分析锅炉存在问题的有效手段。The routine method which used to test the air leakage of the furnace isn t easy to control on the aspects of measure-point dispersing and measurement error.So a new method is brought forward,which is using the principle of heat balance of the air heater to test the air leakage of the furnace.That method does not need to adjust the furnace pressure under lots of situation.The paper offers a convenient and effective means on the scene to test the air leakage of the furnace and to analyze the boiler problem.
