Abstract: An oil burner capable of ensuring normal combustion of quality-deteriorated kerosine. A burner body including a vaporization section is fed with fuel and air from a fuel pump and an air fan, respectively. A combustion control unit controls the fuel pump and air fan to control a combustion quantity in the burner body. The combustion control unit increases the combustion quantity to a combustion level sufficient to permit tar collected in the vaporization section to be burned at a predetermined time interval. Also, the combustion control unit keeps the combustion quantity increased to the combustion level for a predetermined period of time which permits tar collected in the burner body prior to an increase in combustion quantity to the combustion level to be substantially exhausted. This permits the combustion quantity to be intermittently increased, to thereby ensure substantial exhaustion of tar collected in the burner body.

Abstract: A cleaning apparatus for a burner on a motor vehicle energizes a heater of a fuel atomizer for heating and atomizing fuel, when fuel supply to the fuel atomizer is shut off and the speed of rotation of the engine on the motor vehicle is higher than a prescribed level, so that carbon deposits on and in the fuel atomizer will be burned out and removed.

Abstract: There is disclosed a combustion apparatus of a fuel vaporizing type wherein fuel is led to a fuel injector for vaporization and the vaporized fuel is fed to a burner via a gas nozzle for combustion. The combustion apparatus features the provision of a device for removing at a high temperature tar attached in the fuel injector. Preferably, the removal of the tar is accomplished by fuel-empty burning. Therefore, there is no possibility that tar is deposited in the fuel injector, resulting in no faulty or incomplete combustion nor an accident to the combustion apparatus. It is further unnecessary to exchange the fuel injector or a vaporizing core installed therein or clear the interior of the fuel injector. The combustion apparatus demands only the fuel-empty burning device for the removal of tar with high temperature heating and is of simple and low cost structure. Controls are further provided for keeping constant the temperature of the fuel injector during fuel-empty burning.

Abstract: A self cleaning vapor burner for liquid fuel in communication with a combustion chamber. The burner includes an electrically heated evaporating tube. The supply of liquid fuel is periodically interrupted to the evaporating tube wherein the tube is heated to a predetermined cleaning temperature to effect deposits on the evaporating tube wall to ash.

Abstract: A burner of wick type is disclosed which secures user safety by stopping combustion through an oxygen depletion protection function in the event of an oxygen depletion. When tar is accumulated in the wick, the wick is burnt to clean the tar with the liquid fuel supply cut off, thus burning out the liquid fuel contained in the wick. In the process, the combustion temporarily becomes unstable and a great amount of carbon monoxide is generated, resulting in a state similar to oxygen depletion. In a burner with an oxygen depletion protection function, the combustion is stopped during the wick cleaning, with the result that most of the tar accumulated in the wick remains unburnt, adversely affecting both the fuel absorption characteristic and service life of the wick. This invention is such that the oxygen depletion protection function is not operated during the wick cleaning.

Abstract: In the cellar located below an underjet-type of battery of coke ovens are gas distribution pipes. A gas dispensing nozzle is located within each of the separate pipes which extend from a distribution pipe through the regenerators into the burners for a row of heating flues between two coking chambers. These nozzles are cleaned by injecting compressed air from a pipeline that extends parallel to the rich gas distribution pipe. A nipple opposite each nozzle interconnects the air pipeline and the gas pipe. The nipple receives a plug having either an orifice or a nozzle tube to direct compressed air toward the gas dispensing nozzle. A supply header for compressed air extends along the battery of coke ovens and this header is connected by a valve to each compressed air pipeline in the cellar. A controller responsive to a timer operates the valves during regenerative heating reversals for periodic cleaning of the gas dispensing nozzles with compressed air.

Abstract: There is provided a process and apparatus for the production of finely-divided metal and metalloid oxides by flame hydrolysis of corresponding metal and metalloid halides whereby burner fouling is minimized and burner fabrication is facilitated by transpiration of a fuel gas or vapor along the boundaries of each halide-containing stream as it is discharged from the burner into a reaction zone.

Abstract: Fuel gas produced e.g. in a fluid bed gasifier and which comprises deposit-forming materials such as heavy hydrocarbons (e.g. tars) and non-combustible fines is passed via conduits and solid-removing cyclones to a burner for admixture with air and subsequent combustion. Deposits formed in the conduits cyclones and burner are removed by closing off the burner outlet and air inlet, and passing a deposit-removing reactant (e.g. air) into the conduit to oxidize and thereby remove deposits, particularly from the cyclones. Preferably, there are at least two burners for the fuel gas, and they are closed off alternately to remove deposits from their respective conduits and cyclones.
