Wall-mounted gas boilers are used in ordinary houses and apartments. They use natural gas, liquefied gas or gas as fuel, which can not only provide you with heating, but also provide you with sufficient domestic hot water. The power of wall-hung boiler is generally between 18 ~ 35kW, which has dual functions of heating and domestic hot water. When matching, the heating area and hot water consumption of the house should be considered.

When the flue gas pressure from the furnace to the boiler outlet is lower than atmospheric pressure, a negative pressure system is established to make the suction of the induced draft fan greater than that of the blower. On the contrary, when the supply pressure of the blower is greater than the suction capacity of the induced draft fan, micro-positive pressure combustion is formed. Micro-positive pressure combustion can reduce the heat loss of air leakage, but it requires much higher sealing performance of the boiler.

Supercharged combustion boiler is to raise the pressure of combustion flue gas to several atmospheres, and use the pressure flue gas as the working medium of gas turbine to drive generator to generate electricity or air compressor to obtain air with higher pressure as combustion-supporting medium. Combustion at higher pressure can accelerate combustion speed and improve heat transfer effect.

Extended data:

Compared with fuel, natural gas network management has a full origin from the network management of domestic boilers, but if fuel is used, it will take some time to add fuel to the oil storage tank. At the same time, we should also consider the convenience of obtaining fuel sources.

Considering the regional energy, the fuel price is generally low in areas rich in coal-fired resources, which is welcomed by users, while in areas lacking coal-fired resources, natural gas fuel is generally used to pursue environmental protection and high-quality life. Through the above comparison, it is suggested that domestic gas-fired boilers are more environmentally friendly and energy-saving.
