1, Reasons for high voltage alarm
When the internal pressure of the boiler rises to 1.2 times the design pressure of the boiler, the high pressure alarm of the boiler will automatically start. There may be multiple reasons for high pressure, including the following situations:
1. Insufficient water intake: If the water intake or valve is not tightly closed, or if the feed pump malfunctions, it will cause insufficient water intake, resulting in an increase in internal pressure of the boiler.
2. Incomplete combustion: Incomplete combustion can lead to carbon buildup inside the boiler, resulting in poor heat transfer, high internal temperature, and increased pressure.
3. Poor sewage discharge: If the boiler sewage valve is not tightly closed or the sewage pipeline is blocked, it will cause poor water flow, thereby increasing the internal pressure of the boiler.
4. Improper temperature control: If the control system of the boiler malfunctions or the temperature is set too high or too low, it will cause the boiler pressure to rise, triggering a high pressure alarm.
2, Solution to High Voltage Alarm
When a high pressure alarm occurs inside the boiler, timely measures need to be taken to avoid serious consequences. Here are some common solutions:
1. Turn off the feedwater pump: If insufficient water intake leads to an increase in pressure, the feedwater pump should be turned off in a timely manner to avoid further increasing the water level and exacerbating the high pressure situation of the boiler.
2. Dredging the sewage pipeline: If the discharge is not smooth and the pressure rises, the sewage pipeline should be dredged in a timely manner to avoid the sewage flowing back into the boiler and causing the pressure to rise.
3. Adjust temperature control: If the temperature control of the boiler is improper and leads to an increase in pressure, the temperature control system should be adjusted in a timely manner to reduce the boiler temperature and thus lower the internal pressure.
4. Cleaning carbon deposits: If carbon deposits occur inside the boiler, they should be cleaned in a timely manner to restore the heat transfer performance of the boiler and avoid high pressure.
In short, overpressure in boilers is a dangerous situation that requires timely measures to be taken to avoid serious consequences. The above is a detailed introduction to the causes and solutions of boiler high pressure alarms, hoping to be helpful to user.
