Diffusion combustion that is not pre-mixed, but the mutual diffusion of the gas nozzle orifice, and burning. The advantage combustion stability, simple gas appliance structure, but the flame is longer, easy to produce incomplete combustion, heated area carbonation.

That part of the air premixed combustion air prior to combustion in advance is mixed with a portion of the gas, and then combusted. The advantage is clear burning flame, burning strengthen, high thermal efficiency. But unstable combustion and combustion control components require a higher primary air. Gas burners generally burn more such manner.

Flameless combustion air that is required prior to combustion gas has been uniformly mixed with the gas. Once the excess air coefficient is equal to the excess air ratio for complete combustion of the fuel required to obtain oxygen from the ambient air in the combustion process. When a mixture of gas and air to reach the combustion zone to burn is completed in an instant.
