METHOD AND DEVICE FOR FURNACE OPERATION Russian patent published in 2016 - IPC F27B7/36 

Abstract RU 2604741 C2

FIELD: fuel.

SUBSTANCE: invention relates to a method of combustion of the main and the auxiliary fuel in a combustion furnace, to a device for injection of liquid oxygen into the combustion furnace and to the combustion furnace. Method involves introduction of the main fuel and the main oxidizer into the combustion furnace to form the main combustion zone, in which the main fuel is burnt with the main oxidizer, injection of liquid oxygen into the combustion furnace as an auxiliary oxidant to form a separate auxiliary zone for auxiliary oxidizer together with the auxiliary fuel. Disclosed are a device for injection of liquid oxygen into the combustion furnace and a combustion furnace.

EFFECT: provided is the possibility of complete combustion of the auxiliary fuel in the furnace having considerably lower calorific capacity than the main fuel to produce a product of improved quality.
