A comprehensive analysis of the occurrence of water shortage in industrial gas steam boiler
Harm degree of Water shortage accident of Industrial Gas Steam Boiler after Water shortage of Boiler, if handled improperly, it will cause serious damage. That is to say, water leakage will be caused immediately after water shortage (such as quick loading boiler after tubesheet expansion leakage accident); because the dry combustion temperature of tubesheet is very high after overheating, explosion will occur, and the inlet water will cause sharp cooling shrinkage, resulting in cracks and burst.
Cause Analysis of Water shortage accident of Industrial Gas Steam Boiler
Water level monitoring, misjudgment or timely irrigation or misoperation as a result of AWOL or carelessness.
(2) the defect of forming false water level meter itself. If the steam and water connection pipe is blocked, the steam and water connection pipe valve is not opened on the spot or the valve is closed, and the water level meter is not properly installed or seriously leaked.
(3) failure of water supply equipment or pipeline. Such as pump damage, water cut, automatic water supply regulation failure, water supply line blockage, forget to open the valve or check valve failure.
3. The treatment method of water shortage of industrial gas steam boiler (1) according to the judgment of calling water, if there is a slight shortage of water, the operation can be suspended, the water slowly enters the normal water level, and the cause of water shortage is identified and eliminated, before the boiler continues to operate, No other anomalies are checked. (2) if there is a serious shortage of water, the fire must be put out immediately, the boiler must be stopped, the boiler shall be allowed to cool naturally, and the water supply shall be strictly prohibited. When the boiler water temperature drops below 70 ��, the boiler can slowly enter the normal water level, and the boiler can reignite the fire pressure without abnormal conditions.
