DEVICE FOR SIMULTANEOUS AND ALTERNATING BURNING OF P\LUMPY FUEL WITH OTHER KIND OF FUEL Russian patent published in 2004 - IPC

FIELD: device for simultaneous or alternating burning of liquid, gaseous and solid fuels.

SUBSTANCE: proposed device is provided with furnace, fuel supply unit, furnace unit for burning fuel in layer at delivery of primary air; secondary air is fed through cyclone-type primary furnace above fire grate at level of delivery of solid fuel; furnace has combustion chamber and injector for delivery of fuel and primary air. High-reaction fuel is fed to injector. Secondary air is additionally fed through nozzles mounted on furnace walls. Cyclone-type primary furnace is mounted at height equal to 1/3 of height of furnace. Primary furnace is provided with peripheral swirler. Combustion chamber of primary furnace is provided with tangential nozzles for delivery of primary and secondary air. Device is provided with two and more primary furnaces which are mounted opposite each other in such position that jet or vortex flow of secondary air at primary furnace is directed towards jet or vortex flow of secondary air at outlet of opposite primary furnace. Proposed device may work on different kinds of fuel with no interruption in technological process.

EFFECT: enhanced efficiency and ecological safety; reduction of mechanical and chemical incomplete combustion.
