METHOD OF CONTROL OVER BURNING IN A REACTOR AND A REACTOR Russian patent published in 2008 - IPC F23C5/08 F23L15/02 

FIELD: the invention refers to reaction furnace.

SUBSTANCE: the reaction furnace has a body of the furnace having a wall of the furnace, which surrounds a furnace chamber confined in it, totality of reaction tubes envisaged between the pair of opposite wall sections of the mentioned wall of the furnace of the mentioned body of the furnace and located near to each other, passing in one and the same direction, totality of the first burners which are located outside from the mentioned reaction tubes and are envisaged on the mentioned wall of the furnace in the mentioned body of the furnace for burning of fuel in the mentioned furnace chamber, one or more second burners motionlessly fixed at least in one of the pair fields of fastening of the mentioned pair wall sections where the mentioned reaction tubes are envisaged for injecting fuel in the axis direction of the mentioned reaction tubes into the space limited between the two or more adjacent tubes from the number of the reaction tubes, and an unit of a heat-exchanging type for feeding air for burning for discharge outgoing gas from the mentioned furnace chamber outside from the mentioned reaction furnace through an air-permeability regenerative arrangement and feeding air heated to a high temperature with the aid of physical warmth stored in the mentioned regenerative arrangement into the mentioned furnace chamber for burning, at that the method includes stages on which they provide work only to the mentioned first burners for burning fuel for increasing temperature in the mentioned furnace chamber till inside of the mentioned furnace chamber the state of combustion on air will arise having high temperature, provide the work for one or more second burners for burning fuel after the state of burning on air having high temperature is achieved in the mentioned furnace chamber and reduce intensity of burning of the mentioned first burners with increasing intensity of burning of the mentioned one or more second burners in order to achieve necessary state of combustion. The relation of the intensity of burning of the mentioned first burners to intensity of burning of the mentioned one or more second burners is maintained on the level corresponding to the mentioned necessary state of combustion after that mentioned necessary state of combustion is achieved. The relation of intensity of burning of the mentioned first burners to intensity of burning of the mentioned one or more second burners are in the diapason from 80:20 to 0:100. The quantity of air fed into the mentioned furnace chamber by the mentioned unit of heat-exchanging type for supplying air for burning is defined in such a way that average value of concentrations of oxygen in the mentioned outgoing gas is the diapason from 3,5 till 6%.

EFFECT: the invention allows reduce harmful exhausts into the air, increase coefficient of efficiency of the reaction furnace.
