In the operation of electric heating steam boiler, pay attention to the inspection of each part, and observe the pressure and water level. In case of overpressure or water shortage, the boiler shall be shut down, the ash shall be removed to the front edge, and the cold water shall be injected slightly, but a large amount of cold water shall not be poured into the cold water, so as to avoid the occurrence of an accident. In operation, the stoker is not allowed to leave the position without permission, and when the night shift works, no drowsiness is allowed, and the sleeping is not allowed, so as to avoid the occurrence of an accident. Let's get together today to learn about the reason and treatment of the water shortage in the electric heating steam boiler.
Causes of water shortage in electrically heated steam boilers:
The staff of the company furnace are careless and do not supervise the water level enough;
When the furnace staff or maintenance staff scour the water level meter of the electric heating steam boiler or the maintenance water level meter, the steam and water cock are closed by mistake, resulting in false water level;
The staff of the company furnace scour the water level meter in time, resulting in false water level;
Failure of water supply equipment, failure of automatic water supply regulator or interruption of water source, rest of water supply;
The design of water supply pipeline is unfair;
The water supply pipeline is blocked or broken by dirt, and the valve of the water supply system is closed or damaged;
Drain valve leakage or forgetfulness sealing;
Electric heating steam boiler furnace tube or superheater tube, economizer tube ruptured;
The high and low water level alarms fail and do not send out ringtones or light signals.
II. Water shortage treatment of electric heating steam boiler:
When the water level of the electric heating steam boiler is less than the water level, firstly, the method of washing the water level meter is used to determine that the water shortage is still full of water. In case of water shortage, if the water connecting pipe of the water level meter is lower than that of the high-fire field, the boiler shall be shut down immediately, the temperature of the furnace is reduced, the main steam valve and the water supply valve shall be closed. The water capacity is large, and the water-connected pipe is higher than the boiler in the high-fire field of the boiler, and can be called water; the method determines the severity of the water shortage so as to take corresponding measures.
When it is determined that the water shortage is not serious, the water supply to the electric heating steam boiler can be continued, and after the normal water level is restored, the electric heating steam boiler can be started to gradually increase the temperature, and the step-up investment is put into operation. In case of severe water shortage, the boiler should be shut down urgently, and it is strictly forbidden to supply water to the boiler blindly. In no way promise to have a good luck, attempt to conceal the responsibility of causing the water shortage of the boiler, and blind water supply. Such an error often leads to a great disaster, an expansion of the accident, and even the explosion of the boiler and the destruction of the furnace.
