摘要:
Ein Verfahren zum Ansteuern eines Glühzündorgans (14) eines Heizgerätes (12), insbesondere eines Fahrzeugheizgerätes, umfasst die Schritte: a) beruhend auf einer Bordspannung Erzeugen einer an das Glühzündorgan für eine Grund-Vorglühdauer mit einem Grund-Vorglühtastverhältnis anzulegenden Soll-Vorglühspannung (Us), b) dann, wenn die Soll-Vorglühspannung (Us) nicht erreichbar ist, Ermitteln einer Abweichung (ΔU1, ΔU2) zwischen der Soll-Vorglühspannung (Us) und der an das Glühzündorgan (14) angelegten Ist-Vorglühspannung (U1, U2), c) beruhend auf der im Schritt b) ermittelten Abweichung (ΔU1, ΔU2), Ermitteln einer bezüglich der Grund-Vorglühdauer erhöhten korrigierten Vorglühdauer oder/und Ermitteln eines bezüglich des Grund-Vorglühtastverhältnisses erhöhten korrigierten Vorglühtastverhältnisses.

In the case of a burner, in particular coal dust burner (12), comprising a fuel pipe (1), a fuel nozzle (2), at least one ignition and/or heat source (3') and a pipe (7, 10) which conducts an oxygen-containing gas and/or recirculated flue gas, wherein the at least one ignition and/or heat source (3') is arranged in the burner interior and is in the form of or comprises an electric heating and/or ignition device (14') by means of which, exclusively by conversion of electrical current into heat energy, the amount of heat energy required within the burner for the initiation and continuation of the initial pyrolysis and ignition is generated and/or provided in the burner interior, in particular in the region of the fuel ignition site that forms, it is the intention to provide a solution which, dispensing with the use of gaseous, liquid or solid additional fuel, permits frequent start-up and shut-down of the burners of a steam generator of a large-scale thermal power plant in an inexpensive manner with regard to fuel consumption, and provides a burner suitable for this purpose. This is achieved in that a stabilizing ring (9) with toothed ring (15) is a constituent part of the electric heating and/or ignition device (14') arranged in the mouth region (13) of the fuel nozzle (2).
摘要:
A gas turbine combustor assembly includes a primary combustion chamber in fluid communication with a primary fuel injector and a primary air inlet. A torch igniter is carried by the primary combustion chamber, and includes an auxiliary combustion chamber housing comprising a mixing chamber and a throat region converging downstream of the mixing chamber. An air swirler including a plurality of swirl openings surrounding an outlet of an auxiliary fuel injector is coupled to the auxiliary combustion chamber proximate the mixing chamber. An ignition source projects into the mixing chamber of the auxiliary combustion chamber.
摘要:
An ignition assembly for use in pilots for flaring, incineration, and process burner applications, includes a hot surface igniter assembly specifically located in the pilot head or combustion chamber of a flame front ignition system for providing a pilot ignition source. The pilot head is positioned proximally to the exhaust exit of a flare gas stack. The hot surface ignition assembly is positioned proximally to the pilot head. The hot surface ignition assembly passes electric current through a ceramic -insulated element in order to produce heat by induction sufficient to ignite said pilot gas. A thermocouple, or other form of flame sensor, is provided for detecting and a sensing the existence of pilot flame and for controlling the ignition sequence.
摘要:
An ignition device that ignites a mixture including an oxidizer and fuel includes a heating element (1) that has a heat generation region (1a) generating formerly heat to a temperature above the ignition temperature of the mixture (Y) at a tip projected downward from an installation unit (100), a fuel holding unit (2) that encloses the heat generation region (1a), in which the heat generation region (1a) is installed inside thereof and has a through hole (2a) opened to an upper part thereof, and a surrounding wall (3) that forms a space (R) connected to the upper part of the through hole (2a) and has a flame ejection opening (3a) opened from the space (R) to the outside. According to the ignition device, an ignitability of the ignition device can be improved.
