HEAD OF TORCH PLANT Russian patent published in 2006 - IPC F23D14/20 

FIELD: burners.

SUBSTANCE: head comprises detachable housing, injecting burner, and protecting shield. The top section of the housing is provided with axial swirler with inclined blades and outlet part made of a diffuser and ring baffle to define ring space between the housing of the head and ring baffle. The ring space receives alternating air supply and gas supply passages. The outlet part of the ring baffle and outlet part of the air supply passages are inclined to the central section of the head. The bottom section of the air supply passages is provided with openings for the communication with the atmosphere. The bottom section of the gas supply passages is provided with openings for connection with the space of the head. The ring space between the axial swirler and ring baffle receives the ring swirler with bent blades which are inclined in the direction opposite to that of the inclination of the blades of the axial swirler. The gas valve is made of at least three converging branch pipes that are mounted one above the other to define ring chambers. The diameter of the top converging branch pipe is greater than that of the bottom one and smaller than the intermediate branch pipe. The top and intermediate converging branch pipes are mounted to define a ring throttling slot. The branch pipe for supplying gas is interposed between the top and bottom converging branch pipes.

EFFECT: enhanced reliability and efficiency.
