    摘要: A pilot fuel nozzle for a combustor includes an igniter forming a central body extending along a longitudinal center of the nozzle. A nozzle tip includes a plurality of circumferentially spaced fuel passages and a plurality of circumferentially spaced air passages extending to an outer side of the nozzle tip. The central body extends through a center of the nozzle tip for producing a spark to ignite a fuel/air mixture adjacent to the nozzle tip. A plurality of fuel tubes extend along the central body, each of the fuel tubes having an outlet end engaged on the nozzle tip for delivery of fuel from the nozzle tip into a combustion chamber of the combustor An outer sleeve surrounds the fuel tubes and defines an annular space in fluid communication with the air passages of the nozzle tip between the outer sleeve and the central body.

    摘要: A multi-fuel oil furnace system includes a burner that may use waste oil for fuel, and a heat exchanger for providing a warmed air output from the burning of the waste oil. The burner need not require a reservoir for continuously keeping the fuel hot as may be required by conventional systems. The burner may also include a user replaceable unit that may minimize down time of the burner for the user.

    摘要: When a boiler plant (100), which is equipped with an air plenum (104), is in operation, during the startup phase the admission pressure in this air plenum (104) is lowered in terms of time and amount via a blowoff device (106) with respect to combustion air (7) and startup air (105) made available from this air plenum (104). The air coefficient to the burner is consequently reduced. This ensures that, by means of such a near-stoichiometric fuel/air mixture, favorable ignition conditions are provided in the burner and the pollutant emissions during the startup phase are greatly reduced.

    摘要: In a method of operating a swirl-stabilized burner operated with gaseous and/or liquid fuels (12, 16), in which combustion air (7) or a mixture of recycled flue gas (30) and fresh air (29), which mixture is formed by injector delivery, and fuel (12, 16) are intensively mixed by means of a swirl generator (37) and then burned, in the course of which a backflow zone (24), which stabilizes the flame, is formed, starting air (38), which has at least a radial velocity component, is injected during the starting action at the downstream end of the swirl generator (37) in such a way as to be directed from the margin of the burner into the center. The injection of the starting air (38) is switched off after the end of the starting action, so that the burner works in such a way as to be unaffected in normal operation. The invention improves the ignition conditions, increases the flame stabilization, and reduces the pollutant emissions when the burner is being started.

    摘要: The invention provides a combustion device such as a stove which may include a pressurized fuel mixture, such as an aerosol container containing alcohol and a propellant which may comprise a normally gaseous hydrocarbon, such as a liquified petroleum gas. The propellant and air are fed to a combustion zone as a combustion mixture, which is combusted therein in a cold start period to pre-heat the liquid fuel and vaporize it. When the liquid fuel is vaporized by the heat provided by combusting the propellant gas, combustion is continued by combusting the vaporized liquid, e.g., alcohol, fuel. The pressurized fuel composition may comprise a major proportion of alcohol together with a minor proportion of the hydrocarbon propellant starter fuel. The method therefore includes carrying out an initial, cold-start phase of combustion utilizing the propellant as fuel, and a subsequent stage of combustion utilizing the vaporized liquid fuel. Propellant gas, if any, dissolved in or otherwise carried over with the liquid fuel may also be combusted during the subsequent stage of combustion.
