Abstract: In a liquid fuel burner wherein a fuel gasifying member is directly supported by a rotary shaft inserted in a main body of the burner for converting liquid fuel into gasified form, a water evaporation chamber of the annular shape is arranged at the corner of a top portion of the fuel gasifying member and filled therein with a water evaporation promoting material. Water is supplied to the water evaporation chamber and quickly converted into water vapor which is ejected into the fuel gasifying member through steam ejection apertures formed in the water evaporation chamber as the fuel gasifying member is rotated and performs the liquid fuel gasifying function, and the gasified fuel and water vapor form a mixture with air supplied under pressure, the mixture being ejected into the main body of the burner to sustain combustion of liquid fuel in gasified form, so that the consumption of thermal energy can be reduced by using water as part of the liquid fuel.

Abstract: A burner wherein a fuel gasifying member is non-rotatably mounted and disposed in spaced juxtaposed relationship to a gas accumulation chamber formed in a main body of the burner receiving an air supply duct inserted through one side, and liquid fuel scattering means is rotatably mounted at an open end portion of the fuel gasifying member for scattering a liquid fuel in minuscule particles into the interior of the fuel gasifying member and the main body of the burner through a scattering gap. A skirt formed therein with gas ejection slits is mounted at the periphery of the liquid fuel scattering means and has a lower half portion received in the gas accumulation chamber to define a forwardly directed annular gas ejection passageway between the skirt and gas accumulation chamber. A cylindrical air guide may be mounted within the fuel gasifying member and maintained in communication with the air supply duct.

Abstract: A combustion chamber device includes a combustion chamber and a rotatable cup-shaped fuel spreader arranged centrally therein. Liquid fuel is supplied to within said cup for being distributed therein and discharged therefrom and intermixed with an air stream supplied to said combustion chamber to form an air-fuel mixture which then is ignited. The spreader cup is located adjacent a combustion zone in the combustion chamber and provided with an enclosing insulation in the form of a layer of axially flowing air. According to the invention, the fuel spreader cup has a substantially straight and cylindrical inner surface with a circumferential shoulder or threshold adjacent the open end, said shoulder having a radial thickness sufficient for maintaining inside said spreader cup a fuel layer of required depth for obtaining a predetermined fuel supply volume in the cup.

Abstract: An improved fuel injector for a turbine, the injector comprising a conical cup adapted to be rotated and a means for depositing fuel on the internal surface of the cup. When the cup is rotated the fuel is caused to be spread uniformly over the internal surface of the cup as a thin film due to centrifugal force. An air blast is provided externally of the cup and parallel thereto, whereby the fuel reaching the lip of the cup is atomized and directed outwardly at a controlled spray angle. During turbine ignition an air blast is not utilized, thereby allowing a constant spray angle of 180 degrees and permitting the accurate fixed location for the ignition system.
