What is the working principle of gas wall-hung boiler?

When the ignition switch of the wall-hung boiler enters the working state, the fan is started first to form a negative pressure difference in the combustion chamber, and the wind pressure switch sends instructions to the water pump. After the water pump is started, water flow switch sends an instruction to the high-voltage discharger. After the high-voltage discharger is started, the instruction is sent to the gas proportional valve, and the gas proportional valve starts.

Because there is negative pressure in the combustion chamber, natural gas will not be burned together, so deflagration will not occur, quiet ignition can be realized, and dangerous accidents can be avoided. This standard can identify the stability of the furnace.

The gas proportional valve, wind pressure switch and smoke induction switch are interlocked, and the combustion chamber can only work when there is a certain negative pressure gas proportional valve. When the smoke induction switch does not detect waste gas for 5 seconds, the gas proportional valve will be cut off to stop gas supply, thus ensuring the safe use of gas.

Extended data:

Gas wall-hung boilers originated in Europe.

Advantages:

It has many safety protection measures, such as anti-freezing protection, anti-dry burning protection, accidental flameout protection, over-temperature protection, anti-lock protection of water pump and so on. The indoor temperature controller can be externally connected to realize personalized temperature adjustment and achieve the purpose of energy saving.

Function:

Gas-fired wall-hung boiler has a powerful central heating function in the family, which can meet the heating needs of multiple rooms. Each room can set a comfortable temperature at will, and can also decide to turn off the heating of a room as needed, and can provide large-flow constant-temperature sanitary hot water for home bathing, kitchens and other places.
