A MINIATURE LIQUID FUEL COMBUSTOR ABSTRACT The present invention relates to an apparatus for controlling combustion comprising a combustion chamber, a vortex chamber, a plurality of injection points wherein the combustion chamber comprises an inner chamber and an outer chamber which connected to a vortex chamber, whereby the vortex chamber is positioned at the bottom of the combustion chamber and the plurality of injection points comprises at least one fuel inlet and at least one air inlet. Further, the injection points are located at upper portion of the outer chamber allowing tangential flow into the inner chamber for combustion within the inner chamber, whereby the vortex chamber has larger diameter than the outer chamber to increase vaporization rate and mixing rate of the fuel and air.
