HEAT-INSULATED MULTI-REGIME GAS BURNER Russian patent published in 2005 - IPC

FIELD: combustion.

SUBSTANCE: burner comprises housing with valve, ring gas collector coaxial to the housing and provided with one set of detachable nozzles directed at an acute angle to the axis of the burner , pipeline for gas supply, air duct that is defined by the ring gas collector and receives controllable swirler, protecting shield mounted upstream of the gas collector from the side of the furnace with a spaced relation to it, and diaphragm made in block with the face of the gas collector that faces the furnace. The axial space S₁ between the shield and collector and radial space S₂ between the diaphragm and housing are equal to half radial space S₀ between the collector and housing and radial space S₃ between the shield and housing S₀. The radial rotatable blades of the swirler are secured to the hollow axle screwed in the carrier at the front edge of the blades parallel to the axis of their rotation mating to the ring collar in the central threaded bushing of the valve. The direction of rotation of the blades is opposite to the direction of the screw line.

EFFECT: enhanced efficiency.
