Generally speaking, the gas steam generator emergency treatment method

As a steam generator manufacturers have also introduced a lot of relevant knowledge, generally speaking, the protection of gas steam generator is very in place, generally does not appear dry burning, if it occurs should be how to deal with it?

First, stop the use of the furnace in a timely manner

Immediately on the controller direct operation to make the boiler flameout, and turn off the gas control valve in front of the boiler heel, stop the gas supply. The gas boiler and gas valve fully isolated, open the air valve or safety valve to exhaust steam pressure.

If the boiler is shut down due to a low water problem, do not feed water into the boiler. No less water problems, can choose to enter the water discharge alternating ways to lower the temperature and pressure, should maintain the water level, full of water problems should be temporarily stopped to give water, reduce the combustion (will be artificially changed from a large fire to a small fire), open the discharge valve to release water, at the same time to open the main steam pipe and the sub-cylinder on the trap, to avoid a large amount of steam with water, resulting in water flushing.

Stop the furnace link, can not make the furnace cooling rate is too fast, in order to avoid the flue, pressurized parts and expansion of the mouth and other sudden cold damage.

Second, the treatment method

Timely stop the furnace when things happen, because the nature of things are not the same can have the following different methods of treatment:

1. quickly turn off the fire to deal with timely stopping the furnace, first stop the gas boiler, and turn off the natural gas valve to stop the gas supply after the fire, disconnect the main gas valve, to let the pot to keep the water level normal.

2. rapid cooling furnace water treatment, timely shutdown, such as no less water or water leakage problems, can reduce the time to accelerate the cooling to the boiler to give water, sewage to reduce the pressure, the furnace water temperature drops to below 80 ℃, can be discharged from the furnace water, such as boiler less water, shutdown of the furnace must not be selected to rapidly cool the operation, shall not be to the furnace to give water, or there may be a burst.
