Most steam boilers have a certain pressure to output high-temperature steam while heating water. They are special pressure equipment specified in China and implement special operating specifications. Whether the operation meets the requirements will directly affect the life of the boiler, which is why some steam boilers have a short service life, but some can achieve an extremely long service life.
When the wrong operation causes the steam boiler to leak, don't panic, we can save it.
First, the cause
1. The boiler feed water does not have oxygen removal. The high oxygen content in the water causes the oxygen to escape and accumulate in the gas space during the boiler operation.
2. Improper daily operation, when the furnace is shut down, the water supply valve or the main pipeline steam valve is not closed in time, causing the air to enter the furnace, so that when the pressure is increased again, the invading oxygen is not removed in time, so that the oxygen is caused in a hot and humid environment. Long-term corrosion perforation of the pipe.
Second, the standard operation
1. Boiler feed water is deoxidized according to GB1576-2008 standard to reduce oxygen content.
2. When the furnace is shut down, stop the boiler when the boiler is at normal high water level and normal pressure, then close the inlet valve and the main air valve to prevent outside air from invading the furnace.
3. When starting the furnace, first open the main air valve for exhausting. When the pressure reaches 0.1-0.15MPa, close the main air valve to remove the air in the furnace, and then open the main air valve to supply air when the rated working pressure is reached.
4. Strengthen valve maintenance and maintain rigor.
