The fast boiler

Zhengzhou Fangkuai Boiler Factory tells you the reasons for the lack of water in oil and gas boilers

Time : 2021-07-23
In the operation of oil and gas boilers, the drum (shell) contains and maintains a certain amount of water, which can make the steam pressure and boiler water level relatively stable, and is also conducive to the natural circulation of the boiler and the separation of steam and water, which is the basic condition to ensure the safe operation of the boiler .

If there is a serious water shortage in the oil and gas boiler, the tube on the heating surface of the boiler will be overheated and deformed or even burned; the tube bulge leaks and the expanded tube falls off; the steel on the heating surface is overheated or overburned, reducing or losing the bearing capacity, and the tube Blasting; damage to the furnace wall, etc., if improperly handled, it will lead to more terrible consequences.

Zhengzhou Fangkuai Boiler Factory summarized the following more common causes of water shortage in oil-fired gas steam boilers for your reference:
       1. Operators are negligent and lax on water level monitoring;
       2. After the boiler is blown, the blowdown valve is not closed or closed, or the blowdown valve is leaking;
       3. The water supply equipment or water supply pipeline fails, which reduces or interrupts the water supply;
       4. The steam and water connecting pipes of the water level gauge are blocked, the cock leaks or other reasons form a false water level;
       5. Blasting of boiler water wall, convection tube bundle, economizer tube or smoke tube to release water vapor
