ABSTRACT:
A burner for burning a vaporizable liquid fuel, comprising a suction chamber, a combustion chamber, an air inlet to the suction chamber, a vaporizing chamber, a first passage interconnecting the combustion chamber with the vaporizing chamber, a second passage interconnecting the vaporizing chamber with the suction chamber, a liquid fuel inlet atomizer connected to the vaporizing chamber, and a vortex generator at the interface of the fuel inlet atomizer, first passage, and vaporizing chamber, the generator swirling hot combustion gases from the first passage into a vortex, 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, the path having sufficient width 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, thereby producing a mixture for burning in the combustion chamber.
