COAL-WATER FUEL COMBUSTION DEVICE Russian patent published in 2010 - IPC F23K1/02 

FIELD: heating.

SUBSTANCE: burner device for combustion of coal-water fuel includes lined combustion chamber and cooling chamber shielded with steaming tubes, which are interconnected to each other by means of bypass openings. Also pneumatic atomisers and blast nozzles; at that, combustion chamber having cylindrical shape with horizontal rotation axis and flat edge walls, near the symmetry axes of which there arranged are gas crossover openings, the area of each of which is 0.2 to 0.6 of the area of edge wall of combustion chamber, is arranged inside cooling chamber so that they have common front wall on which there mounted are fuel atomisers performing both separate and combined supply of various types of fuel and primary oxidiser, and common lower wall on which there installed is ash collector made in the form of a hopper, and blast nozzles are installed inside combustion chamber with a tangential supply of oxidiser, and in addition, central heat-resistant insert is installed, the cross dimension of which is 0.2-0.5 of equivalent diametre of combustion chamber.

EFFECT: providing environmental safety, effective combustion of coal-water fuel and improving operating reliability of the furnace.
