Natural gas would be the fuel of gas fired boiler, the mixed method of natural gas and air can have influence for the burning intensity, flame length and flame temperature. According to the different mix method, the gas fired boiler for sale burning may be separated into three types:
1, part premixed air combustion: this process of combustion will mix partial air and gas upfront before combustion. A benefit is the fact that burning flame is clean, burning is reinforced, thermal efficiency is high, but the combustion is instability, power over the main air and burning element demand is higher.
2, diffusion combustion: this combustion needs no burning for instance pre-mixed combustion, but also in the gas jet diffuses and burns. What's so great about this type of gas-fired boiler combustion is stability, gas appliance is straightforward in structure, but flame is long, easy to produce incomplete combustion, heating surface carbonation.
3, flameless combustion: The combustion mode namely gas needs air and gas mixing before burning. An excess air coefficient is equivalent to the extra air coefficient if the fuel combustion, the combustion process doesn't have to acquire oxygen through the surrounding air, when the gas and air mixture attain the combustion zone after combustion straight away.
