Abstract: A portable warming assembly includes a canister and a lid that is removably attachable to the canister for closing the canister. A roll of solid fuel is positionable inside of the canister and the roll of solid fuel is comprised of a combustible material. A container containing a liquid fuel is provided and a pre-determined amount of the liquid fuel is pourable onto the roll of solid fuel when the roll of solid fuel is positioned in the canister. In this way the liquid fuel enhances combustion of the roll of solid fuel. A plurality of rocks is provided and each of the rocks is positionable on top of the roll of solid fuel when the roll of solid fuel is positioned in the canister. Each of the rocks heats the ambient air when the roll of solid fuel and the liquid fuel are burned for heating an interior space.

Abstract: The invention comprises a fuel package comprising a vessel, a fuel, a combustion-restricting choke plate and a sealed lidding.

Abstract: The portable out door heater burns fuel such as propane from a pressurized gas fuel tank. The fuel enters an entrainment tube through a nozzle orifice that is coaxial with the cylindrical entrainment tube axis. Air enters the entrainment through air entry apertures and is entrained with the high velocity fuel stream. The air and fuel mixture passes from the entrainment tube into a coaxial cylindrical burner supply tube. The supply tube has a smaller diameter to accelerate movement of the air and fuel mixture. A cylindrical combustion chamber receives the air fuel mixture moving tangentially to the combustion chamber inside wall. A ring inside the chamber retards movement of the fuel charge. The fuel oxidizes at a temperature that reduces odors and converts carbon monoxide to carbon dioxide. The products of combustion pass through a silencer and into an area to be heated. A choke and igniter initiate combustion.

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 invention comprises a fuel package comprising a vessel, a fuel, a combustion-restricting choke plate and a sealed lidding.

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: An oil burner of the heat radiation type is disclosed which is capable of effectively preventing clouding of the inner surface of a heat-permeable cylinder with moisture, contaminants contained in combustion gas such as soot and tar, and the like during at the ignition and combustion operation.The oil burner includes a communicating means for establishing the communication between an air supply passage and a space between a heat-permeable cylinder and an outer combustion cylinder, which comprises a top plate for a pot having through-holes formed at the portion thereof above the air supply passage and a top plate for a housing having through-holes formed at the portion below the space, to thereby allow air to be introduced directly from the air supply passage to the space and upward flow along the inner surface of the heat-permeable cylinder.

Abstract: A pot burner, which in an undefined sloping position with rocking movements functions well, particularly in vehicles and vessels, because the vaporing surface of the fuel is defined and because the vapored fuel is well mixed with air in a first cage, which is enclosed by a second cage.

Abstract: A device which includes a porous burner head capable of containing a liquid fuel in a liquid state and in which air is supplied to the surface of the burner head to vaporize and burn the fuel contained therein. The burner head is made of a heat-resistant porous material having extending therethrough minute channels which are predominantly up to 100 .mu.m in diameter and give the burner head a porosity of at least 25%. The burner head is capable of raising the liquid fuel at a rate of at least 0.001 g/cm.sup.2.min to a height of up to 70 mm. The use of the burner head assures clean combustion and high combustion efficiency.

Abstract: A heater includes a first housing which forms a fuel reservoir and a base support to maintain the heater in an upright position. A first elongated hollow or tubular member is secured to the top of the first housing with its lower end communicating with the interior of said first housing and extends upwardly therefrom. A second housing is mounted on top of the first housing and is provided with opening or port means to communicate the top of the first housing with the second housing. Port means in the second housing also communicates the second housing with the first elongated tubular member. A second elongated, hollow or tubular member is mounted on the second housing and extends upwardly therefrom. Its lower end communicates with the top of the second housing for communicating air to the second housing. Valve means are provided in each the first and second elongated hollow members for selectively controlling communication therethrough.

Abstract: A vaporizing type oil burner adaptable for use in forced flue type kerosene space heaters for household use and other heating equipment, including a fuel vaporization promoting plate made of a thin sheet of porous material and covering the entire area of the bottom of a vaporizer pot, an oil feeding device for feeding oil to the vaporizer pot which is capable of regulating the volume of oil fed to the pot, an oil diffusing device for control oil fed to the pot to the entire area of the fuel vaporization promoting plate, and a combustion air supply device. The fuel vaporization promoting plate is formed with a multitude of pores having surfaces functioning as surface means for vaporizing oil and receiving the heat of radiation generated by a flame, so that the time from initial combustion to steady state combustion following the starting of combustion can be shortened, the size of the burner can be greatly reduced, and incomplete combustion of the oil can be prevented when the burner is tilted.

Abstract: A flat flame burner comprises an air swirling chamber, an air supply tube provided for the air chamber for introducing combustion air thereinto in the peripheral direction of the air chamber so as to produce a swirling air stream in the chamber, a fuel gas supply tube disposed in the air chamber and having inlets centrally of the space for the swirling air stream and a flame opening positioned at one side in the direction of axis of the swirling air stream coaxially with the swirling air stream, the flame opening being defined by a wall having a thin portion around said opening and a flat outer face.
