BURNER Russian patent published in 1994 - IPC

FIELD: power engineering. SUBSTANCE: body 1 with tangential air feed branch pipe 2 at the inlet is parted by shell 3 into central and peripheral channels 5 and 6 respectively. Gas feed pipes 7 are equidistantly circumferentially spaced relative to each other in channel 5, the pipes have inlet sections 8 parallel to the axis of body 1, passed through branch pipe 2 and connected to low-calorie gas manifold 9, and outlet section 10 located behind the outlet section of shell 3 and fastened to each other by cone disk 11 which is adjacent to front ends of pipes 7, the disk overlaps the flow cross sections of pipes 7. Rectangular plates 12 are spaced at a distance from back end 4 of branch pipe 2 in the clearances between pipes 7. the plates are adjacent to disk 11 by end edges and to generatrices of pipes 7 by side edges to form with the side walls of the pipes tangential compartments converging to the periphery and coincident with the direction of air swirling in branch pipe 2. Notches are made in disk 11 on the periphery of the compartments. Outlet sections 10 of pipes 7 communicate with the cavity of body 1 through apertures 14 formed in the pipes and adjacent to plates 12, the apertures are directed along the plates to the periphery of body 1. EFFECT: reduced nitrogen oxides discharge. 3 dwg
