What principle does the wall-hung boiler rely on to keep warm?

Gas-fired wall-hung boilers use natural gas, artificial gas or liquefied gas as fuel. The fuel is output through the burner, and after burning in the combustion chamber, the heat is absorbed by the heat exchanger. When the circulating water in the heating system passes through the heat exchanger, it is repeatedly heated, thus continuously outputting heat to the building and providing heat source for the building.

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.

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

Expanding the advantages of data wall-hung boiler: solar terms

The wall-hung boiler itself is the key to solar terms, and a gas-saving wall-hung boiler can save you a lot of follow-up expenses. First of all, national energy efficiency labeling is necessary. Of course, the higher the energy efficiency, the better, but the state stipulates the highest level 2. Secondly, the original imports are more exhaust gas. Because the gas mixing ratio in each region is different, and the economic conditions of residents are also different.

Therefore, many foreign brands have been localized after entering China. Voorburg, Germany improved the German design to adapt to the national conditions of China, and changed the small fire exhaust and high flue temperature commonly used in European wall-hung boilers into multi-burners, which reduced the flue temperature and greatly reduced energy consumption.
