Abstract: An evaporator burner (100) for a mobile heating unit which is operated using liquid fuel is provided, said evaporator burner having: a mixture preparation region (2) for the mixing of fuel with combustion air to form a fuel-air mixture; a fuel feed (1) for feeding liquid fuel to the mixture preparation region (2); a combustion air feed (B) for feeding combustion air to the mixture preparation region (2); at least one evaporation surface (8) to which the liquid fuel is fed and which serves for the evaporation of the liquid fuel; a conversion region (3), positioned downstream of the mixture preparation region (2) in terms of flow, for the conversion of the fuel-air mixture into combustion exhaust gases (A) with a release of heat; and an exhaust-gas recirculation means (10; 210) for the recirculation of combustion exhaust gases (A) into the mixture preparation region (2).

Abstract: A combustion type heater of this invention includes fuel distribution means 11 for distributing a fuel to the whole surface of a wick 10, disposed upstream of the wick in a fuel passage. The fuel distribution means comprises fuel distribution grooves 15 and a fuel dispersion plate 16 having a large number of holes bored therein. The fuel distribution means can quickly supply the fuel to the whole surface of the wick. To shorten the heating time of the wick, the heater of the present invention uses a wick heating glow plug 14b outside an ignition glow plug 14a, or a planar heater 18, for heating the wick.

Abstract: A closed furnace vaporizing burner and a feed therefor suitable for adapting to a closed fireplace, transforming it into a liquid fuel fireplace. The invention comprises two distinct portions: The fuel feed comprising the inlet 1, an air-liquid separator 2, an injector tube 3 terminated by two downwardly bent small-diameter tubes 30, a cooling tube 4, a holding and protection tube 13, two protective tubes 16 and 18 or a heat-recovery cooler 39, and a support 10. The combustion assembly comprises an air feed and hearth support box 20, a fan 22, a combustion pot 26, a receptacle 27, horizontal disks of grid, or expanded metal, or perforated sheet metal 31, radial fins 36, a transparent ceramic glass tube 38, a reflecting screen 47, and in a variant, air injection rings 41 and transparent ceramic glass tubes 42.

Abstract: A liquid fuel burner apparatus which comprises a fuel distributing member of a generally conical configuration mounted within a housing, along with means for feeding a liquid fuel to an upper end of the fuel distributing member to allow the liquid fuel to form a film on the outer surface. A vaporizing aperture is formed in the outer surface and a gas supply conduit supplied with a pressurized gaseous material to atomize the fuel for ignition. The unburned fuel is then collected and recycled back to the burner. The apparatus permits the burning of material which may contain small particles which would otherwise clog the nozzle of a conventional apparatus.

Abstract: Burner for a gaseous fuel, provided with separate supply lines for fuel and oxidizing gas, the oxidizing gas being tangentially fed into a cylindrical swirl chamber, which is connected to a burner bowl through a mixing channel, the fuel being radially supplied at the connection of the swirl chamber to the mixing channel. The burner is optionally provided with an integrated heat exchanger. A composite burner system is disclosed, made-up of burners as described above and optionally provided with a plate which isolates the burners from the surrounding area and which indirectly heats the surrounding area.

Abstract: An aspirated wick atomizer nozzle device having a nozzle body and a screen wire wick sandwiched between the an outlet surface of the nozzle body and the inside surface of a nozzle cap. A liquid entering the nozzle body through a fuel inlet passes by a wicking action of the screen wire wick to a fuel and air exit port where it is entrained and atomized by a gas exiting the nozzle body through an air outlet orifice.

Abstract: Oil heater for burning of waste oil or other like petroleum liquids through vaporization of the fuel resulting in total fuel burn and maximum BTU. Combustion air enters the center of a combustion chamber enclosure through a combustion air wand resulting in air flow in all directions. The wand includes a plurality of spaced holes in a closed annular air channel allowing for escape of air to the combustion chamber and a diffuser plate circumferentially affixed to the wand including a plurality of spaced holes in the diffuser plate for spreading and mixing resultant vapors and gases for burning at the level of the wand. A submerged pump in a fuel storage tank provides for even fuel flow to a center point above the air wand in addition to even air flow by a blower. A vaporizer pan in the bottom of the chamber provides for boiling of the fuel with its resulting vaporization and total burn of residue and ash.

Abstract: A liquid fuel combustion apparatus comprises a combustion cylinder, a fuel reservoir, a housing, a blower and an electrical ignition heater. The reservoir is disposed inside the cylinder to store a liquid fuel supplied from outside of the cylinder. The housing is disposed outside the cylinder to create a space therebetween and has an end wall opposite to an end wall of the cylinder. The blower is disposed outside, and in a spaced apart relation to, the housing and supply air to the space. The heater is supported by the end walls and ignite liquid fuel stored in the reservoir.
