摘要:
Die vorliegende Erfindung betrifft ein Brennersystem für ein Fahrzeug, umfassend eine Prozesskammer zur Vermischung und/oder Verbrennung eines Brennstoffs, insbesondere eines flüssigen Brennstoffs, mit einem Prozessgas, insbesondere Luft, ein mit der Prozesskammer direkt oder indirekt in Verbindung stehendes Brennstoffzufuhrsystem zur Versorgung der Prozesskammer mit dem Brennstoff und ein mit der Prozesskammer in Verbindung stehendes Prozessgaszufuhrsystem zur Versorgung der Prozesskammer mit dem Prozessgas, wobei das Prozessgaszufuhrsystem eine Konditionierungseinrichtung zur Beeinflussung zumindest einer Temperatur des Prozessgases aufweist.
摘要:
A fuel injector 100 for a gas turbine engine includes a monolithic nozzle body 102 that defines within its interior one or more fuel circuits 110. Each fuel circuit includes an inlet 112, an outlet orifice 114, a main passage 118 fluidly coupling the inlet with the outlet orifice, and a branch passage 120 connected to the main passage. The branch passage 120 connects to the main passage downstream of the inlet and upstream of the outlet orifice to form an effective metering flow area that is smaller than the flow area of the outlet orifice.

A fuel atomizer that includes a housing having a fuel inlet and at least one primary orifice positioned at the inlet, wherein the at least one orifice configured to disperse a stream of fuel into a plurality of fuel droplets. The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices.

A nozzle (16) for a fuel injector can include an outer air swirler (24) having an inner surface with the outer air swirler (24) having a groove (34) on the inner surface and a prefilmer (28) located concentrically within the outer air swirler (24) with the prefilmer (28) having at least one detent finger (36) to engage the groove (34) on the inner surface of the outer air swirler (24). The nozzle (16) can also include a fuel swirler (30) located concentrically within the prefilmer (28) and configured to convey fuel to a forward end of the nozzle (16) with the fuel swirler (30) having at least one tab (38) extending axially at an aft end, and an inner air swirler (32) having a cylindrical forward end (40) located concentrically within the fuel swirler (30) and an aft support (42) extending radially outward to contact the outer air swirler (24) with the cylindrical forward end (40) contacting at least one tab (38) of the fuel swirler (30) to hold the fuel swirler (30) in place.

A gas turbine engine (10) fuel nozzle (100) includes an axis of symmetry (143) extending therethrough, the nozzle body (110) including a first passage (142) extending coaxially therethrough, a second passage (152), and a third passage (162), the second passage circumscribing the first passage, the third passage formed radially outward of the second passage, and a nozzle tip (112) coupled to the nozzle body, the nozzle tip including at least one primary discharge opening (170) in flow communication with the first passage, at least one secondary discharge opening (172) in flow communication with the second passage, and at least one tertiary discharge opening in flow communication with the third passage.
摘要:
A burner for an exhaust purifying device includes a tube, an air supply port for supplying air for combustion into the tube, a fuel supply port for supplying fuel into the tube, and an ignition portion. The tube includes a premixing chamber for mixing air for combustion and fuel to generate a pre-mixed air-fuel mixture, a combustion chamber for combusting the pre-mixed air-fuel mixture to generate post-combustion gas, and a discharge port for discharging the post-combustion gas. The ignition portion ignites the pre-mixed air-fuel mixture in the combustion chamber. The tube further includes a swirling flow generation unit arranged upstream of the premixing chamber for generating a swirling flow of which the center direction corresponds to a fuel injection direction and a diffusion unit arranged downstream of the swirling flow generation unit in the premixing chamber for diffusing the fuel incorporated in the swirling flow.
