An oil burner or oil furnace is a heating device which burns heating oil, diesel fuel or other similar fuels. The fuel is atomized into a fine spray usually by forcing it under pressure through a nozzle. This spray is usually ignited by an electric spark with the air being forced through by an electric fan. ==Fuel injection== Fuel is injected into the combustion chamber by a spray nozzle. The nozzles are usually supplied with high pressure oil. Because of problems with erosion, and blockage due to lumps in the oil, they need frequent replacement, typically every year. Fuel nozzles are usually rated in fuel volume flow per unit time e.g. USGal/h (U.S. Gallons per hour). A fuel nozzle is characterized by three features: * Flow at 7 bar pump pressure (e.g. 0.65 USGal/h) * Spray characteristic (e.g. "S") * Spray angle (e.g. 60 °) Alternatively fuel may be passed over a tiny orifice fed with compressed air. This arrangement is referred to as Babington atomiser/nozzle, named after its inventor Robert Babington.〔(【引用サイトリンク】url=http://www.rexresearch.com/babingtn/babingtn.htm )〕 As the oil flows over the nozzle, the fuel needn't be under any great pressure. If the pump can handle such the oil may even contain lumps such as scraps of food. Because it is only compressed air that passes through the orifice hole, such nozzles do not suffer much from erosion. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「oil burner」の詳細全文を読む スポンサード リンク
