The working mode of the gas steam boiler is a device that uses the high heat required when the gas generates heat, and then burns the gas sufficiently. In the process of gas combustion, it needs to be mixed with a large amount of air, but it can be burned through different methods. Zhengzhou Fangkuai Boiler Factory has summarized the three combustion methods of gas-fired steam boilers. After comparison, you can see that the boiler using which combustion method is more suitable for your needs.
One is the diffusion combustion method, which does not mix in advance, but diffuses the gas at the nozzle mouth and then burns it. This kind of combustion method of gas boiler can achieve sufficient stability, and does not have high requirements for burning appliances, and the structure is simple and simple. However, due to the long flame, incomplete combustion is very simple, and carbonization is very simple in the heated area.
The other is a partial air combustion method that requires premixing. Part of the air and gas are mixed in advance, and then burned abundantly. 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, it is very necessary to choose this kind of combustion method.
There is also a flameless combustion method that uniformly mixes the space before combustion with the gas in the gas boiler. When this method is used, the oxygen required by the gas in the combustion process does not need to be obtained from the surrounding air, and only needs to reach the combustion zone with the air mixture to complete the instantaneous combustion end.
Users can choose different combustion methods according to practical requirements, and then promote sufficient combustion, the effect of gas boilers can also be fully utilized, and the energy consumption required for production can also be reduced.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance. Join us at Booth No. B1-08 from November 5–7, 2025 at the Jakarta Convention Center.
The event brings together EXPO BOILER, EXPO BIOMASS, EXPO PUMPS & VALVES, and EXPO CRANE — creating a comprehensive platform for technology exchange and business collaboration across the industrial heating and energy sectors in Southeast Asia.
At the exhibition, we will present our integrated solutions including biomass boilers, industrial steam systems, and full power plant EPC services. Our products emphasize:
