摘要： The invention relates to a combustion-chamber arrangement for gas turbines, having an annular combustion chamber connected to at least one burner and leading into a turbine space, an annular-combustion-chamber wall which defines the annular combustion chamber being of double-shell construction, and an inner shell of the annular-combustion-chamber wall being composed of lining elements releasably arranged on an outer shell of the annular-combustion-chamber wall, and a gap space through which a cooling medium can flow being formed between the inner shell and the outer shell of the annular-combustion-chamber wall. In order to develop such a combustion-chamber arrangement to the effect that it is possible to exchange individual lining elements of the inner shell of the annular-combustion-chamber wall with comparatively little outlay, it is proposed with the invention that the lining elements be of trapezoidal design having in each case a fastening structure, formed in each of the longitudinal sides and directed outward, for releasably fastening to a corresponding mating structure of an adjoining lining element and/or a supporting structure connected to the outer shell.

摘要： A combustor can simultaneously reduce the amount of NOx exhaust and combustion oscillation. The combustor has an internal cylinder which accommodates a premixing nozzle and an external cylinder which accommodates the internal cylinder, and includes an air flow passage which supplies air from a compressor to the premixing nozzle. The air flow passage is provided with a punched metal plate near the maximum velocity fluctuation position whereat the velocity fluctuation of the air flow increases to a maximum.

摘要： A gas turbine engine for generating electricity having low NOx emissions that includes a turbine system linearly and axially connected by a power shaft to a compressor section and having a combustion section mounted vertically relative to the turbine section and the compressor section. The combustion system includes a plurality of individual combustors mounted in a circular or annular array around the upper cap or dome of the combustion system, each of said combustors being a dual mode, two-stage, emitting low levels of NOx. Each combustor exhausts its combustion gases into a common central plenum chamber that is vertically oriented relative to the turbine engine centerline. The plenum provides the hot gases to the turbine blades through an annular chamber 360 degrees around the shaft. The gas turbine engine vertical combustion system provides for a highly efficient, low nitric oxide emissions while allowing for uniform mixing of the combusting gases powering the turbine system.

摘要： A radial flow engine has at least one rotor with an internal cavity that includes a vaporization section and a condensation section. The condensation section is disposed radially inward toward the shaft and the vaporization section extends radially outward adjacent to the surface of the rotor blade. The vaporization section includes a series of pockets for dispersing the cooling fluid within each blade, and a cascaded series of capture protrusions to distribute the liquid coolant to the successive radially-arrayed pockets. A working system includes a centrifugal compressor which feeds a compressed air fuel mixture to an annular combustion chamber that, in turn, feeds the combustion gases along a radial direction to impinge on the surface of the cooled radial flow rotor. Optionally, the system is a regenerative system including a heat exchange sub-assembly which couples heat from the exhaust stream to a position between the compressor and combustion chamber. The invention also includes a compressor, or a turbine, or both a compressor and a turbine with a rotor cooled by internal vaporization and condensation of a recirculating medium, and systems wherein such a cooled compressor and cooled turbine assembly operate together, either as a stand-alone engine or combustion system, or as a core engine between other input and output stages. The core engine may be retrofitted to improve the efficiency or increase the power of an existing plant.

摘要： A microturbine power generation system includes an electrical generator, a turbine and a compressor intermediate the generator and the turbine. Rotating components of the turbine, compressor and electrical generator are secured together by a tie-bolt. The tie-bolt is pre-stressed such that faces of the rotating components of the turbine, electrical generator and compressor maintain contact during high-speed, high-temperature operation of the system. The tie-bolt includes a thermally less conductive short portion that is secured to the rotating component of the turbine wheel, and an elongated portion that extends through the rotating components of the compressor and electrical generator. The short, thermally less conductive portion of the tie-bolt inhibits heat from propagating from the turbine end towards the compressor. The short, thermally less conductive portion can be a titanium rod that is inertia-welded between the elongated portion of the tie-bolt and the rotating component of the turbine.

摘要： A gas turbine (5) according to the invention, which comprises a main combustion chamber (10), a cooling system for air cooling of at least the guide vanes (26, 29) and guide rings (28, 38) of various stages (25, 27) of the gas turbine (5), and a main gas passage, also includes a further combustion chamber (34), which is arranged downstream of the main combustion chamber (10) as seen in the hot-gas main direction (H). The cooling air (15) used to cool a stage (25) of the gas turbine which is arranged upstream of the further combustion chamber (34) is fed into this further combustion chamber (34). In this context, it is particularly advantageous for the cooling air (15) used to cool the various stages (25, 27) of the gas turbine (5) to be fed for combustion. This makes it possible, inter alia, to increase the output of the gas turbine (5) without having to increase the supply of fuel.
