The gas boiler is a kind of diffusion combustion method in the working process. It does not mix in advance. During operation, the gas is mainly diffused at the nozzle orifice, and then burned. This kind of combustion method can achieve stability, and the requirements for burning appliances are not high, and the structure is simple. However, due to the longer flame, incomplete combustion is prone to occur, and carbonization is prone to occur in the heated area.

　　It requires a pre-mixed part of the air combustion method, a part of the air and gas are mixed in advance, and then burned. The advantage of using this combustion method is that the burning flame is clearer and the thermal efficiency is higher; but the disadvantage is that it is unstable during combustion and requires higher control of combustion components. If it is a gas burner, this kind of combustion method is required.

　　It is mainly a combustion method that uniformly mixes the space before combustion and the gas in the gas boiler. The oxygen required during the combustion process of the gas does not need to be obtained in the surrounding air, as long as the air mixture reaches the combustion zone. Achieve the completion of combustion. Users can choose different combustion methods according to actual requirements, thereby promoting the progress of combustion, the role of gas boilers can also be brought into play, and the energy consumption required for production can also be reduced.

　　The function of the air supply system of a gas boiler is to send some air speed and volume into the combustion chamber. Its main components are: shell, fan motor, fan impeller, air gun fire tube, damper baffle, cam adjustment mechanism, diffuser Plate.
