Background
The economizer is a device which is arranged at the lower part of a tail flue of a boiler and used for recovering waste heat of discharged smoke, and has the characteristics of reducing the temperature of the discharged smoke, saving energy, improving the heat efficiency and the like. The economizer is divided into a steel pipe type and a cast iron type according to the structure, wherein the steel pipe type economizer is widely applied to high-parameter and high-capacity boilers. The steel pipe type coal economizer consists of parallel elbow pipes (commonly called coiled pipes) which are horizontally arranged. Because the high-temperature flue gas contains a large amount of ash particles, when the boiler is used, the large amount of ash particles pass through the steel pipe type economizer and rub against the inner wall of the steel pipe type economizer, so that the steel pipe type economizer is abraded, and the economizer is leaked; according to data statistics, the worn and leaked part of the economizer is generally positioned at the snake-shaped tube bundle elbow of the high-temperature section. Therefore, it is necessary to alarm the leakage of the economizer in a preventive manner.
The leakage alarm of the existing economizer adopts an observation method to alarm. The observation method is that the temperature of flue gas is obviously reduced after leakage occurs, or the relevant detection data of the dust remover is abnormal, so that the leakage of the economizer is judged, but the method has great contingency, and the leakage can be detected through other data only when the leakage is serious.
