Safety valve

In the boiler protection, the safety valve is the last line of defense, when the boiler pressure exceeds its limit, according to the set pressure specified in the safety valve design, the steam pressure is discharged to ensure the normal operation of the boiler.

Protect the temperature.

Temperature control is an important part of the safe operation of the boiler, especially the gas-fired hot water boiler is particularly important for the temperature control and protection of the steam boiler, and the over-temperature regulation and protection of the hot water boiler. Bimetal temperature control flameout protection is a common temperature protection device for boiler.

In order to prevent the occurrence of explosion accidents, the fuel (gas) boiler must be set up flame protection device, its role is to monitor the combustion in the furnace (including ignition, when the ignition fails or the combustion is extinguished in the middle, the electric hot water boiler is generally re-ignited within 5 seconds, in 1 second operation, close the oil (gas) solenoid valve, connected and issued a sound and light alarm signal, at this time the blower continues to work, Purge the remaining combustible gas in the furnace, purge 20 to 30 seconds after, automatically cut off the blower and various auxiliary equipment power supply, boiler stop operation). Includes flame monitor and flame monitoring device. The function of the fire monitor is to signal the presence or interruption of the fire to the control equipment.
