The control unit is configured to drive the gas regulating valve in real time.

Abstract: A fuel reformer burner for a polymer electrolyte membrane fuel cell (PEMFC) system includes a first tube through which a fuel for a fuel reformer is supplied and a second tube through which anode-off gas (AOG) is supplied from a fuel cell stack. The second tube is not connected to the first tube, and an inlet line through which an air is supplied is connected to the first tube.

Abstract: The present invention provides a burner (10) for a heater for combustion of a hydrocarbon liquid. The burner (10) comprises a combustion chamber having a combustion zone (17) for combusting the hydrocarbon liquid and at least one tank portion (13, 15) for containing an amount of the hydrocarbon liquid. The or each tank portion (13, 15) is positioned adjacent the combustion zone (17) and arranged to feed the hydrocarbon liquid into the combustion zone (17). The or each tank portion (13, 15) is at least in part filled with a filling material having a plurality of portions that pass through the interior of the or each tank portion (13, 15).

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: The burner comprises a cylindrical body defining an oil vaporizing chamber, an inlet on the body for oil, and inlet on the body for air and a bed of imitation fuel such as ceramic briquettes. The bed of imitation fuel receives vapor from the chamber for combustion around the imitation solid fuel. Heat generated by such combustion is arranged to vaporize oil in the chamber received rom the oil inlet.

Abstract: A burner for combusting vaporized liquid fuel includes a combustion chamber which is open at an upper end and a side wall which defines air supply openings through which air is delivered into the combustion chamber. A thermally conductive body is disposed in the combustion chamber and extends upwards to the upper end of the chamber. The body enhances the combustion of the fuel within the combustion chamber. A disk-shaped annulus defining gas flow openings is mounted in the combustion chamber and extends radially inwards from the side wall to proximate the body, such that substantially all gas flow past the annulus occurs through the gas flow openings.

Abstract: A combustion chamber for heating systems operated with liquid fuel can be used as vehicle heaters but also as heating systems for e.g. cooking purposes and whose control range is expanded as compared with known devices. The combustion chamber includes two sections separated from the combustion space by a plate with a passage opening. Depending on the purpose of use, a different flame guiding insert is arranged between the combustion space and the combustion chamber.

Abstract: A burner system, for example at a heating unit, comprising a burner of evaporation type for liquid fuel, for example Diesel oil, where fuel is intended via an inlet (5) to be supplied into a combustion space, preferably at the bottom (3) thereof, which combustion space preferably is substantially cylindric and open at the end (4) opposite to said bottom (3), and where preferably an ignition member (6), for example a glowing filament, is provided for the initial ignition of evaporated fuel, and where means (9,16,17,18) are provided for the supply of air to the combustion space.

Abstract: An improved waste oil heater that includes a vaporizer pan having a mounting ring, a replaceable aluminum foil piece mounted on the ring to form the bottom of the pan and a member mounted on the ring to provide threads, a tool threadingly engageable with the threaded ring member for breaking the pan loose from the bottom wall of a burner pot and removing the ring with caked residue thereon for purposes of cleaning, the burner pot having a novel arrangement of apertures for flow of air into the pot, and solid state electronic control apparatus to control the feed of waste oil that automatically compensates for variations in viscosities and caloric values found in a variety of used oils and automatically discontinues the feed in the event the flame in the burner pot goes out.

Abstract: A burner comprising a substantially diamond-shaped housing with in the interior one or more partitions defining with the two housing walls opposite the burner mouth two or more similarly diamond-shaped burners, the partition most remote from the burner mouth having a flame opening the rim of which being bent away from the burner mouth, the burner mouth being so large that air flows entering through air supply orifices near said mouth reach to the middle or slightly beyond thereof and the bottom being recessed over some degrees in the center between the end walls of the burner.

Abstract: A pot-type burner is equipped with baffle plates for establishing recirculation zones within the burner for efficiently mixing air and gas in a conventional manner. The burner construction is improved by removing the combustion ring, and in its stead adding an annular dome. This initiates sonic pulsations, sustained within a heat exchanger housing which has critical dimensions relative to the burner parts. The pulsations produce improved combustion.
