Abstract
1413807 Heat guns D S ZAGOROFF 10 Nov 1972 [10 Nov 1971] 52038/72 Heading F4T In a hand-held heat fun for directing a flow of heated air against a work object, fuel gas issues from a jet 1 into a jet pump 3 to entrain and mix with ambient air A, the fuel/air mixture passing via a pressure recover passage 3c, constructed to convert the mixture velocity head into a pressure head, into an internal combustion chamber 5 having walls arranged to co-operate with said pressure head to convert combustionrelated gaseous expansion into velocity head of the combustion products, the outlet portion of the gun being constructed to produce a jet pump effect whereby the combustion products entrain and mix with ambient air to produce a flow of heated gases at a desired temperature. The jet pump effect at the outlet is enhanced by providing a tubular member, having an air inlet 7a, around the outlet of chamber 5. The tubular member may have openings (19), Fig. 6 (not shown), in its sidewall and may be adjustable to control the spacing between its outlet and the combustion chamber outlet, thereby adjusting the temperature of the gas flow at the outlet of the gun. The combustion chamber has a bluff body flame holder 8 and has a flow cross-section which decreases towards its outlet which may be an elongate slit or an array of slits (90), Fig. 7 (not shown). In alternative form, the pressure recovery passage leads into a plurality of combustion chambers each having a slit-shaped outlet, with the outlets in an array wherein the long axis of each outlet slit passes through the centre of the array.
