Abstract

The invention relates to auxiliary equipment for reburning combustion products. The technical result is that of accelerating the ignition of fuel and improving fuel combustion in a furnace. A device for reburning combustion products in a furnace is arranged above a combustion unit inside the body of the furnace and is in the form of a hollow body with a bottom inlet hole and a top outlet hole, on the side wall of which hollow body there is formed a horizontal row of evenly distributed air holes. Rectangular protrusions are formed to the right- and left-hand sides of each hole on the inside of the body of the device, said protrusions serving to feed supplementary air, which comes in via the holes, from the outer holes of the furnace into the body of the device, providing for accelerated incineration of residual combustion products without formation of a vortex in the air flows.

Claims (4)

1 . Device for reburning furnace combustion products is arranged above a combustion unit in the form of a hollow body with a bottom inlet hole and a top outlet hole, on the side wall of which hollow body there is formed a horizontal row of evenly distributed air holes, wherein, rectangular protrusions are formed to the right- and left-hand sides of each air hole on the inside of the body of the device said rectangular protrusions serving to feed supplementary air, which comes in via the air holes, from the outer holes of the furnace into the body of the device, providing for accelerated incineration of residual combustion products without formation of a vortex in the airflow.

2 . The device according to claim 1 , wherein the rectangular protrusions are parallel to each other.

3 . The device according to claim 1 , wherein the body of the device is designed in the form of a truncated cone and/or a truncated pyramid and/or a truncated parallelepiped and/or a cylinder.

4 . The device according to claim 1 , wherein the thickness of the rectangular protrusions is less than the thickness of the body of the device.
