What should I do if there is a sudden power failure during the normal operation of the hot water boi

Low temperature (65 degrees) hot water boiler, stop the burner work, some boiler equipment is interlocked; If there is a steam pump, open the furnace door, reduce the furnace temperature appropriately, and the low-temperature boiler generally does not need special treatment.

For high-temperature water boilers (105 degrees), the minimum water pressure of the boiler must be maintained, which generally refers to the pressure at the inlet of the boiler circulating water pump, to ensure that the highest point of the heating system will not be caused by power failure and loss of pressure, resulting in high-temperature water gasification of the top pipe of the pipeline system, remember. In case of power failure, the electric water pump cannot be used to replenish water and maintain pressure, let alone release hot water from the system to cause the system to lose pressure. High-temperature water heating pipes are difficult to design and install.

Low-temperature water is generally sufficient for expansion tanks. The low-temperature water heating system uses the air pressure tank as the water replenishment and constant pressure, and the practice of abandoning the expansion tank is an important reason for the designer's lack of common sense in operation and management difficulties. is the lack of design experience.

Young people.

Immediately stop the inlet flue gas heat source, the water in the boiler can ensure that it is not burst, if the steam opening valve is automatic, you can manually open the steam outlet valve to reduce the pressure of the system, according to the steam boiler design specifications, the steam boiler must be installed for sudden power failure of the water supply system, the small low-pressure boiler uses the "water jet", and the slightly larger one uses the "steam reciprocating pump". Large boilers have backup diesel generators.

There is also a small boiler that is hand-fired and has no electrical equipment, and the power outage does not have a great impact on its operation. Some boilers are equipped with a feed tank, which does not need to be stopped immediately if the water in the feed tank can be used for a short period of time.

The normalizing furnace has a power outage, and how to deal with the products in the faulty furnace.

Hello dear, according to the loss of socks you described, the treatment of the products in the faulty furnace is as follows: in case of sudden power failure when the boiler is burning, the attendant first inspects the pressure and water level gauge, and greets the electrician class in time to clarify the cause of the power outage and make a record. If the power outage is long, it may cause a shortage of water in the boiler, so you should pay close attention to pressing the fire.

Don't rush to water after the call, you should call for water first, and then open the water pin spike plug valve, if there is no pot water flowing out, indicating a serious lack of water. After the lack of water, the steel plate (pipe) has been overheated, and even burned red, if the water blindly enters the hot metal and tears, the accident will occur immediately. Wait for the furnace hall and furnace tube to drop to room temperature before adding water.

The sudden water supply system of the boiler should be immediately load-shedding, the load reduction is to reduce the steam supply as much as possible and reduce the amount of water replenishment, and contact the dispatcher (value chief) and the steam turbine professional in time to determine when the feedwater will be restored. If it can be resumed immediately, it is possible to maintain low-load operation during the load shedding operation. If you are unsure or cannot recover in a short time, you should stop the furnace immediately.

Pay attention to close the drain water exhaust valve tightly after the furnace is stopped to maintain the boiler water level. For fluidized bed boilers and chain furnaces, pressure fire operation can be adopted, and hot start can be carried out after the feed water is normal.

Step 1: Immediately press the fire, or cut off the fuel.

Step 2: Strictly monitor the liquid level, and strictly prohibit the dry pot of the underground railway Step 3: After reducing the pressure, it can also be appropriately supplemented with fire water and other emergencies ( Note that different boilers have different requirements, and must be in accordance with the regulations.

The most important point: If the pot is dry, it is strictly forbidden to put water on it, otherwise the boiler ** will not be guaranteed. There is only one way to deal with this situation: turn off the heat and let it cool down slowly.

I think it is to close the inlet valve from the boiler to the steam engine, but the safety valve of the boiler must act, at this time, it is necessary to determine whether the furnace should be stopped according to the situation of the water source.

If the water level is not high, seal the furnace immediately and close the outlet valve.

Summary. Dear, hello, I'm honored to have you this question, this is normal, after the heating furnace works to the set temperature, the water pump will still keep turning, in order to let the water in the pipeline circulate and flow, so that the thermostat senses whether the water temperature drops as a whole, when the water temperature in the pipeline is lower than the set temperature 15 degrees, and after 3 minutes, the machine will automatically start to work, not the machine failure, please rest assured to use.

2.If you don't need the machine's water pump to work all the time, you can turn off the switch of the machine (Note: For models with a 24-hour dial timer, when the timer is working, the heating stops and the pump also stops during the set shutdown period).

Is it normal for the water heating furnace pump to wait until about 2 minutes after the ceasefire to run?

Dear, hello, I'm honored to have your question, this is normal, after the heating furnace works to the set temperature, the water pump will still rotate, in order to let the water in the pipeline circulate and flow, so that the thermostat senses whether the water temperature drops as a whole, when the water temperature in the pipeline is lower than the set temperature 15 degrees, and after 3 minutes, the machine will automatically start working, not a machine failure, please rest assured to use. 2.If you don't need the machine's water pump to work all the time, you can turn off the machine's switch (Note:

Models with a 24-hour dial timer, when the timer is working, the heating stops the elevation and the water pump also stops during the set shutdown period).

Thank you! I newly installed the Ou Debao wall-hung boiler, according to the requirements of the merchant burial staring at the mill bucket, when there is no one at home, the observation is observed, and the temperature is adjusted to 40 degrees! The wall-hung boiler will not ignite the heat, but the water pump will start working every two or three minutes, if it is normal, I will not bother you!

Thank you! Okay, dear, no problem.

Thank you again! You're welcome, dear, and I wish you a happy life!

What is the matter with a natural gas boiler that starts running for a period of time and then stops and then starts automatically immediately after a power outage?

Natural gas boiler burner frequent lead leakage automatic restart? Not locked? This is because the gas pressure is close to the value limited by the minimum gas pressure switch.

The opening of the solenoid valve is followed by a continuous pressure drop, which causes the pressure switch to be powered off and the valve to be closed and the burner to shut down; The pressure rises again, the lowest pressure switch is energized, the burner is started again, the solenoid valve is opened, the pressure is reduced again, and the lowest gas pressure switch is powered off and shut down; Cycle. It is recommended to reduce the working pressure of the minimum gas pressure switch, clean or replace the gas filter, increase the gas delivery pressure, and check whether the outdoor gas pressure regulator box is frozen.
