摘要： A burner (27) of a gas turbine engine (10) includes a cylindrical basket (60) comprising an air flow reversal region (86). The flow reversal region ends at an air inlet plane (84) of the basket. The burner also includes a flow conditioner (90) disposed in the flow reversal region transecting an air flow (80) flowing non-uniformly through the flow reversal region, the flow conditioner being effective to mitigate variation of the air flow entering the basket across the inlet plane.

摘要： A pre-mixing burner (10) for a gas turbine engine having improved resistance to flashback. Fuel (32) is supplied to a pre-mixing chamber (24) of the burner from a plurality of fuel outlet openings (34) formed in fuel pegs (36) extending into the flow of air (30) passing through the chamber. The fuel outlet openings are formed to direct the fuel in a downstream direction at an angle (A) relative to the direction of the flow of air past the respective fuel peg. This angle imparts a downstream velocity vector (VD) for increasing the net velocity of the air and a normal velocity vector (VN) for directing the fuel away from the wake (44) formed downstream of the fuel peg. Alternate ones of the fuel outlet openings along a single fuel peg may be formed at respective positive (A) and negative (B) angles with respect to a plane (46) extending along the wake in order to minimize the size of the wake. The propensity of the burner to support upstream flame propagation and flashback is thus reduced by increasing the net air velocity, by minimizing the amount of fuel entrained in the wake, and by minimizing the size of the wake.
摘要翻译：一种用于燃气涡轮发动机的预混合燃烧器（10），其具有改进的抗回火性能。燃料（32）从形成在延伸进入通过该室的空气流（30）的燃料栓（36）中的多个燃料出口（34）供应到燃烧器的预混合室（24）。燃料出口开口形成为相对于通过相应的燃料栓的空气流的方向在下游方向上以相对于空气流的方向（A）引导燃料。该角度赋予用于增加空气净速度的下游速度矢量（VD）和用于引导燃料远离形成在燃料栓的下游的尾流（44）的正常速度矢量（VN）。沿着单个燃料栓的燃料出口开口中的替代燃料出口可相对于沿着尾流延伸的平面（46）以相对的正（A）和负（B）角度形成，以便最小化尾流的尺寸。燃烧器支持上游火焰传播和回火的倾向因此通过增加净空气速度来减少，通过最小化在尾流中夹带的燃料的量以及通过使尾流的尺寸最小化来实现。

摘要： A combustor for a gas turbine is provided having a nozzle assembly located at one end and a combustion chamber defining a second end of the combustor. A venturi is positioned within the combustor, between the nozzle and the combustion chamber. The venturi defines a passageway therein having a first side facing the nozzle and a second side facing the combustion chamber. Compressed air is directed into an inlet in fluid communication with the first and second sides of the venturi passageway. The venturi passageway directs the compressed air from the inlet in opposite directions within the first and second sides of the passageway for cooling the venturi.

摘要： An aft liner seal for a combustor for a gas turbine includes an inner shell having an inner and outer surface and central axis. The aft liner seal has an outer shell positioned over the inner shell that has an inner and outer surface and central axis coaxial with the inner shell. One of the outer surface of the inner shell or the inner surface of the outer shell has grooves angled relative to the central axis. The angled grooves and adjacent portions of the inner surface of the outer shell or the outer surface of the inner shell form cooling passages. The cooling air exits the cooling passages at an exit angle that is matched to a swirl angle of the combustor flow. Matching of the exit angle and the swirl angle minimizes shear of cooling air with respect to flow exiting the combustor liner.
