FIELD: power engineering. ^ SUBSTANCE: device for supply of gases into furnace has flow path made of inlet confusor, rectilinear section and outlet diffuser, each section of flow path has rectangular section, at the same time in this outlet section of confusor, width relates to height as 6:1, and diffuser along width is separated into five curvilinear channels, in which one is arranged in device centre, and others are located symmetrically relative to it. Outlets of two side and two middle channels are arranged at the angle of 90 to outlet of central channel. ^ EFFECT: increased efficiency of fuel and air mixing and operational reliability by reduction of high-temperature effect at furnace walls. ^ 4 dwg |
