FIELD: light engineering. SUBSTANCE: burner has housing, mixer, and incandescent grid. The housing consists of flange, cover, flame tube secured to the flange, and protecting casing with openings interposed between the flange and cover. The mixer is positioned inside the individual casing whose inner space is in communication with the atmosphere. The cover and flange of the burner are flat and interconnected via intermediate stands. The protecting casing of the burner is made up as a grid and secured to the intermediate stands. The casing of the mixer is mounted on the flange and at least partially mounted inside the flame tube. The inner space of the mixer casing is connected with the atmosphere through the opening made in the casing wall. The protecting grid is defined by a spirally wound wire that is secured to the intermediate stands. EFFECT: improved design. cl, dwg |
