Abstract of the Disclosure A burner for burning a vaporizable liquid fuel, comprising a housing, a suction chamber in the housing, a combustion chamber in the housing, with combustion chamber inlet and outlet, a mixing chamber in the housing between the suction chamber and a diffuser, the diffuser connecting the mixing chamber and the combustion chamber inlet; an air inlet to the suction chamber for directing air under pressure into the suction chamber, a vaporizing chamber having an inlet from the combustion chamber and an outlet, a first passage interconnecting the combustion chamber with the vaporizing chamber inlet, a second passage interconnecting the vaporizing chamber outlet with the suction chamber, a vaporizable liquid fuel inlet atomizer connected to the vaporizing chamber at the vaporizing chamber inlet, and a vortex generator at the inter- face of the fuel inlet atomizer, first passage, and vaporizing chamber inlet, the generator swirling hot combustion gases from the first passage into a vor- tex, into which vortex the fuel inlet atomizer directs atomized liquid fuel, the first passage, vortex generator, vaporizing chamber, and second passage together defining a recirculation path for hot combustion gases from the com bustion chamber to the suction chamber, the path having sufficient width to provide in conjunction with the air inlet enough recirculation to maintain blue-flame combustion, whereby the fuel will be vaporized by hot combustion gases as it passes through the vortex generator and the vaporizing chamber, the air inlet creating a suction which draws hot combustion gases and vaporized fuel from the vaporizing chamber through the second passage and suction chamber into the mixing chamber for mixing with the air, thereby producing a combus- tible mixture for burning in the combustion chamber.
