    摘要: A method for compressing gaseous fuel is disclosed. The method includes, ingesting gaseous fuel into a chamber, ingesting air into the chamber and mixing the gaseous fuel with the air, igniting and partially combusting the resulting mixture of gaseous fuel and air in a confined space such that a predominant fraction of the gaseous fuel is not combusted, causing an increased temperature and therefore an increased pressure of the fraction of the gaseous fuel which is not combusted, and discharging the resulting compressed gaseous fuel. Moreover, a compressor is provided including a casing, a rotor with at least three vanes, an inlet for gaseous fuel, an outlet for gaseous fuel, an air inlet and an igniter. The rotor is placed in the casing such that at least three variable-volume chambers part-bounded by the vanes are formed during a rotor revolution.

    摘要: A fuel injector arrangement for fluid fuel combustion apparatus comprises a conduit 31 for the flow of an airstream, a conduit 56 for the flow of fluid fuel to a housing 15 incorporating a fuel plenum chamber 25, the fuel plenum chamber 25 having at least one inlet orifice 22 and at least one outlet orifice 34 in substantially direct alignment, the inlet orifice(s) 22 being connected to the conduit 31 whereby, in use, air in the airstream flows into the plenum chamber to thereby force fuel out of the plenum chamber via the outlet orifice(s). The airstream may constitute a secondary airstream, there being, in use, a primary airstream which flows around and beyond the housing in a conduit 10 to receive the fuel forced out of the fuel plenum chamber.

    摘要: A method of establishing part-load operation is proposed for a turbine group. This gas turbine group consists essentially of a compressor unit (1), of an HP combustion chamber (4) downstream of the compressor unit (1), of an HP turbine (5) downstream of this HP combustion chamber (4), of an LP combustion chamber (8) operating by self-ignition and arranged downstream of the HP turbine (5), the hot gases (10) of which LP combustion chamber (8) being admitted to an LP turbine (11). The temperature at outlet from the HP turbine (5) remains essentially the same due to the reduction of the fuel quantity in the LP combustion chamber (8) to zero. Furthermore, the fuel quantity of the HP combustion chamber (4) remains approximately constant during the reduction of the fuel quantity in the LP combustion chamber (8) so that the temperature at inlet to the HP turbine (5) likewise remains constant.

    摘要: A fluidically-controlled valve is provided. The fluidically-controlled valve includes a main flow channel with a main flow entrance, a flow exit and a constricted channel section located between the main flow entrance and the flow exit. The fluidically-controlled valve also includes a control flow channel including a jet forming control entrance, a first branch channel, a second branch channel, a common channel section, and a convex channel wall. The common channel section follows the control entrance, the first branch channel emerges from the common channel section and leads to the main flow entrance, the second branch channel emerges from the common channel section and leads to the constricted channel section, and the convex channel wall extends from the common channel section into the first branch channel. The fluidically-controlled valve can be used in bypasses present in turbines or in swirlers of gas turbine combustors.

    摘要: A burner for a gas-turbine engine has a frustoconical burner shell, at least two swirler arrangements, which are connected to the shell and are spaced apart around the circumference of the shell between its two ends, and a combustion chamber disposed downstream of a wider end of the shell. Each of the swirler arrangements includes an air swirler and a pre-combustion chamber disposed downstream of the air swirler, and a longitudinal axis of each swirler arrangement intersects a line parallel to, and spaced apart from, the longitudinal axis of the shell. The swirler arrangements are preferably connected to the shell at the same axial point.

    摘要: A combustor for a gas turbine engine comprises an annular combustion chamber having radially outer and inner rows of fuel injectors disposed concentrically in the combustor head wall. Injectors in one of the rows are in angular registration with spaces between injectors in the other row. Each fuel injector produces a fuel/air mixture having a swirling motion, and has a downstream mixing duct. Each mixing duct opens into the combustion chamber through the combustor head wall and has a length sufficient to allow at least partial mixing of the fuel/air mixture before entry to the combustion chamber as a divergent swirling stream. Mixing ducts in the first and second rows of injectors have longitudinal centerlines oriented to coincide with generating rays of respective first and second imaginary conical surfaces. These conical surfaces intersect at an included angle within a primary combustion zone in the combustion chamber, whereby injectors located in different rows are angled towards each other in the downstream direction and the divergent swirling streams of fuel/air mixture coming from different rows cross in the combustion chamber in an interdigitating manner. This creates a strong mixing interaction between the streams from different rows and enhances uniformity and rapidity of combustion in the primary combustion zone.

    摘要: A fuel arrangement for a combustion apparatus, comprises at least one passage for the flow of fluid, the passage being of substantially annular cross section, being defined by a radially inner wall and a radially outer wall and having an inlet region and an outlet region. The inlet region incorporates a plurality of vanes adapted to modify a flow pattern of a fluid entering the inlet region, such that fluid passing from the inlet region to the outlet region has a composite flow pattern having both an axial component and a rotational component about the longitudinal axis of the passage.

    摘要: The object of the invention is to create a simple and compact fuel feed for a gas turbine having an annular combustion chamber. In addition, the operational reliability of the gas turbine is to be improved. According to the invention, this is achieved when only one central main-gas feed line (15) and one central pilot-gas feed line (16) are connected to the annular combustion chamber (1). A main-gas ring line (13) and a pilot-gas ring line (14) are formed in the interior of the gas-turbine casing (5) or a burner hood (3) known per se. These ring lines (13, 14) are connected upstream to the main-gas feed line (15) and the pilot-gas feed line (16) respectively and downstream to the annular combustion chamber (1). (FIG. 1)

    摘要: In a gas turbine combustion chamber which surrounds the rotor as an annulus and therefore has the shape of an annular combustion chamber, the front wall (10) is equipped with a number of burners whose ends occupy a uniform plane. These burners form a double ring (10b, 10c) on the front wall (10). In each ring, the same direction of rotation is present in the burners and this is opposite to the adjacent ring. In addition, two burners at a time are alternately displaced outwards and inwards in each ring in order to achieve a favorable flow field for combustion. The number of burners on the front wall (10) is divided into a larger quantity of piloting burners (A1, A2 ) and a smaller quantity of piloted burners (B1, B2).
