摘要:
The invention relates to a start-up injector for a turbine engine combustion chamber, said injector comprising: a fuel injection circuit; and a fuel ignition circuit including a fuel injector supplied by the fuel injection circuit and a spark plug (101) for igniting the injected fuel. The start-up injector is characterised in that it also comprises: a partitioned enclosure including a first compartment (106) in which the fuel is ignited by the spark plug (101) and a second compartment (107) separated from the first compartment by a thermally conductive partition (105); and a main combustion start-up circuit which includes at least one fuel injector supplied by the fuel injection circuit and opens into the second compartment (107) of the enclosure such as to inject the fuel against the wall (105). The invention also relates to a combustion assembly and a turbine engine comprising at least one such start injector.

The present invention relates to a system for utilizing liquid fuels, such as diesel and gasoline, in a catalytic reactor for producing clean heat from the fuel. In particular it relates to a fuel injection system for a catalytic burner (310, 313). It includes preheating elements (308′, 309, 315; FT) for preheating the catalytic burner (310, 313) and primary fuel supply elements (307) for supplying fuel to the catalytic burner (310, 313). The preheating elements (308′, 309, 315; FT) and the primary fuel supply elements (307) are provided in separate compartments (310, 312), the compartments being connected with each other via a channel (CH).

Zur Erzeugung eines zündfähigen Brennstoff-Luft-Gemisches weist ein Verdampfer für flüssigen Brennstoff innerhalb eines Strömungsraumes (3) für Verbrennungsluft einen Verdunstungskörper auf, dessen von der Verbrennungsluft umströmte Oberfläche mit Brennstoff benetzbar ist. Als Verdunstungskörper dient eine umwälzbare Kugelschüttung (4), deren sich jeweils am Rande der Kugelschüttung befindende Kugeln (16a) mit temperierbaren Wänden (25) des Strömungsraumes (3) in wärmeleitender Verbindung stehen. Die Kugeln (16) der Kugelschüttung (4) werden in einer drehbar gelagerten Umwälzeinrichtung (19) bewegt. Zur Benetzung der Kugeln (16) mit Brennstoff dient die zum Strömungsraum (3) geführte Verbrennungsluft, die flüssigen Brennstoff in feiner Verteilung enthält. Der Verdampfer ist in Figur 1 schematisch dargestellt.
摘要:
A method and device for combustion of liquid fuels is presented which uses a plurality of rotating hydrogen flames to blast atomize and ignite a mechanically dispersed stream of the liquid fuel. This combustion method and device are particularly suited for heavy oil fuels, such as vegetable oils, which are not well burned using conventional burner technologies. This combustion method involves establishing a zone of combusting hydrogen and projecting a mechanically atomized dispersion of the liquid fuel into and through this zone of combusting hydrogen.
摘要:
Process for combustion of a liquid Fischer-Tropsch derived hydrocarbon fuel wherein the following steps are performed: (a) obtaining a mixture of liquid hydrocarbon droplets in an oxygen containing gaseous phase, (b) evaporating the liquid hydrocarbon droplets in a cool flame at a temperature of between 300 and 480 °C to obtaining a gaseous mixture comprising oxygen and hydrocarbons, and (c) total combustion of the gaseous mixture obtained in step (b).
