BURNER UNIT Russian patent published in 2003 - IPC

FIELD: power engineering; burners for motor-car industry. SUBSTANCE: proposed burner unit is provided with at least two newly introduced additional cylindrical nozzles abutting against main cylindrical nozzle, their axes being parallel to main-nozzle axis; main and additional nozzles are provided in vicinity of contact between them with aligned longitudinal slits; longitudinal deflecting projections are disposed on intersection line of cylindrical surfaces in direction of air flow; at least one row of longitudinal slits are made on side surfaces of additional nozzles; eddy-current generator is shaped as envelope surface formed by equal-radius cylindrical surfaces coaxial with additional nozzles or at least two symmetrically disposed holes are made in butt-end wall of combustion chamber for introducing cylindrical nozzles in the latter, their axes being parallel to combustion-chamber axes; each nozzle is provided with individual vortex generator; eddycurrent generator surface is formed by equal-radius cylindrical surfaces coaxial with additional surfaces. EFFECT: enhanced power capacity of burner unit. 2 cl, 7 dwg
