FUEL COMBUSTION METHOD, AND GENERAL-PURPOSE BURNER Russian patent published in 2014 - IPC F23D17/00 F23D14/02 

FIELD: power industry.

SUBSTANCE: fuel combustion method involves supply of air flow, supply of fuel flow of the first type via the first channel, ignition of the flow of fuel of the first type so that the first flame is obtained, as well as supply of flow of fuel of the second type via the second annular channel located almost coaxially to the first one and having a variety of side jet outlets in the outlet part to obtain the second flame. The first channel is located in the second channel; supply of air flows and all types of fuel is adjustable; supply of fuel flow of the first type is performed at almost stopped air flow, and supply of fuel flow of the second type is performed via the second channel to obtain the second flame, thus gradually increasing its pressure till it is equal to or is more than pressure of flow of fuel of the first type, at subsequent increase of supplied air flow preventing lift-off of the first and/or the second flames.

EFFECT: invention allows effective combustion of associated petroleum gas of any composition and reducing emissions of hazardous substances to atmosphere.
