Abstract: For a heater operated by means of liquid fuel, a vaporization burner is provided that has a large-volume active first vaporization part for the very volatile components of the fuel and a large-surface second vaporization part for the least volatile fuel components. The two vaporization parts are separated from one another by a fuel-impermeable material, such as ceramics, so that any occurring coke formations at the second passive vaporization part cannot migrate to the first vaporization part. As a result, the operating reliability and the service life of such a vaporization burner are improved.

Abstract: A carbon particulates cleaning device comprises a carbon particulates catching means, a fuel injecting means, a fuel retaining means for retaining the fuel injected by the fuel injecting means near the carbon particulates catching means, a fuel igniting means for igniting the fuel retained by the fuel retaining means, and a gas blowing means which blows gas for maintaining the fuel burning and applying the heat of the burning fuel into the carbon particulates caught by the carbon particulates catching means. The carbon particulates caught by the carbon particulates catching means are effectively burnt and eliminated by supplying gas which is heated due to the burning heat of the fuel ignited by the fuel igniting means.

Abstract: A heating flue for a coke oven includes a flow plate to replace the base in the heating flue. The thickness of the flow plate is greater than the thickness of the flue base and disposed above a chamber which is divided into two halves in a gas-tight manner by a central web of refractory material. Each chamber communicates with ducts that feed preheated air from regenerators during rich-gas firing and feed preheated air and lean gas during firing with lean gas. The height of the chamber to the thickness of the flow plate is a ratio within 0.3 to 0.7, preferably 0.5. The flow plate has a plurality of bores each with a cross-sectional area which, when compared with the cross-sectional area of the plate, forms a ratio of between 20 and 200, preferably 30 to 60. The diameter of a cylindrical bore is between 10 and 60 millimeters, preferably 20 and 50 millimeters.
Abstract: Apparatus for burning spirit or similar liquid fuels.A draught or burner tube (16) has a flange (18) defining a gap (32) in relation to a ring spaced below the flange and supported thereby. The container is engaged with the ring from below, an exposed surface of a fuel-absorbing mass (28) being located inside the ring. A gap is open at the periphery of the flange and the ring so that combustion air is drawn to the draught or burner tube through the gap along the exposed surface of the mass together with fuel vapors evaporating therefrom.

Abstract: An incinerator for combustible fumes in a mixture of such fumes and air wherein the fumes are raised to incineration temperature by combustion of a normally liquid fuel such as oil. The fumes and air mixture is first heated, preferably by heat exchange with the combustion chamber, to the vaporization temperature of the liquid fuel which is injected in atomized form into the heated fume and air mixture. The fume and air mixture along with the vaporized liquid fuel is then drawn through a fan which substantially homogeneously disperses the vaporized liquid fuel in the fume and air mixture and passes the homogeneous mixture to a combustion zone having a flame grid through which the liquid fuel-containing mixture passes. The liquid fuel in the mixture is ignited at the flame grid to form a flame curtain which raises the temperature of the fume and air mixture to incineration or oxidation temperature of the fumes. The fumes are thus oxidized and can thereafter be exhausted to the atmosphere.
Abstract: A heat input device for a heat engine comprises a combustion device which is adapted to support surface burning of a fuel and oxidant mixture and a heat exchanger which is adapted to transfer the heat from the hot surface against which the surface burning takes place to the working fluid of the engine.
