RADIANT HEATER

FIELD: heat-power engineering; continuous or cyclic heating of large buildings. SUBSTANCE: heater has burner, U-shaped radiator, fan, exhaust device, reflector load-bearing frame and suspension system. Fan is mounted before burner of mixing chamber and U-shaped radiator; elements for curtain jet cooling of wall are mounted at points of sections subjected to excessive stresses. Mixing chambers are brought in communication with exhaust device before fan by means of pipe line provided with adjustable throttle valve and distributor. Lateral surface of distributor is provided with nozzles whose diameter (d) and angle of attack (α) are changeable. But each nozzle satisfies equation d/sinα=const,. Rectangular gusset plates are mounted before nozzles in flow section for angular displacement about their axis of symmetry. Mixing chamber before U-shaped radiator and curtain jet cooling elements are brought in communication with pressure chamber of fan by means of manifold of pipe line provided with adjustable throttle valve and distributor having holes in its lateral surface. Holes of mixing chamber are provided with nozzles made in form of cylinders brought out beyond distributor and blanked off on both ends; they have slots in area of distributor and hole in flow section; angle between axis of hole and axis of nozzle is ψ(0
