    Abstract: A two-stage fuel nozzle assembly (56) for a gas turbine engine. The primary combustion region (120) is centrally positioned and includes a fuel injector (122) that is surrounded by one or more swirl chambers (132, 160) to provide a fuel air mixture that is ignited to define a first stage combustion zone. A secondary combustion region is provided by an annular housing (168) that surrounds the primary combustion region (120) and it includes a secondary fuel injector (126) having a radially-outwardly-directed opening (172) and surrounded by an annular ring (128) that includes openings (194) for providing a swirl chamber for the secondary combustion region (124). Cooling air is directed angularly between the primary and secondary combustion zones to delay intermixing and thereby allow more complete combustion of the respective zones prior to their coalescing further downstream. The primary combustion region (120) is activated during idle and low engine power conditions, and both the primary (120) and secondary (124) combustion regions are activated during high engine power conditions.

    Abstract: An air-fuel burner includes a heat-transfer tube, an air-fuel mixing chamber, and an air-fuel nozzle. The air-fuel nozzle is coupled to the air-fuel chamber to communicate a combustible air-fuel mixture into a combustion chamber defined between the air-fuel nozzle and the heat-transfer tube. The combustible air-fuel mixture, when ignited, establishes a flame in the combustion chamber to produce heat which is transferred through heat-transfer tube to an adjacent medium external to the heat-transfer tube.

    Abstract: A heat exchanger for burning fuel oil having vanadium and for preventing melting of vanadium complexes formed from burning fuel oil includes a first (28) and a second (30) stage. Contained within each stage is a duct burner (18) that heats gas flowing through the heat exchanger by burning fuel having vanadium and a cooling component that cools gas heated by the duct burner. Within each stage the temperature of the gas is maintained about below the melting point of vanadium complexes. Consequently, the vanadium complexes do not achieve their corrosive molten state. This invention also includes a method for burning fuel oil containing vanadium and preventing the melting of vanadium complexes by heating and cooling the gas in a plurality of stages.

    Abstract: The invention relates to a combustor (1) for a gas turbine engine, particularly for a gas turbine having sequential combustion. The combustor (1) comprises a combustor wall (4) defining a mixing region (5) and a combustion region (6). The mixing region (5) comprises at least one first inlet (2) for introducing combustion air into the mixing region (5) and at least one second inlet for introducing fuel into the mixing region (5), the combustion region (6) extending downstream of the mixing region. The mixing region (5) crossing over to the combustion region (6) in a transition region (14).
    A baffle (9) extends from the transition region (14) generally in the downstream direction (15) forming at least one space (10) between the combustor wall (4) and the baffle (9).
