摘要： In heat generators and burners, it is frequently necessary to realize discontinuous cross-sectional expansions of a flow duct. When the flow (U) passes over the step (10) formed in the wall (8) of the flow duct, coherent lateral separation vortices form which are propagated almost undamped downstream of the step and frequently represent the cause of thermo-acoustic vibrations of high amplitude. In accordance with the invention, vortex-generating elements (20) with a lateral pitch dimension (t) are arranged on a line transverse to the main flow (U) a distance (s) upstream of the step (10). Given an expedient selection of the pitch dimension (t), the lateral coherence of the separation vortex is enduringly destroyed.

摘要： In a combustion chamber consisting essentially of an inflow zone (5) and a combustion zone (11) and having self-ignition, the inflow zone (5) has vortex generators (100), of which a plurality are arranged next to one another over the periphery of the duct through which flow occurs. A premixing zone (7) follows downstream of the inflow zone (5), into which premixing zone (7) a gaseous and/or liquid fuel (9) is injected as secondary flow into a gaseous main flow (4). Between premixing zone (5) and the downstream combustion zone (11), the transition is characterized by a jump (12) in cross-section which induces the initial cross-section of flow of the combustion zone (11). The fuel (9) is injected via a number of fuel lances (8) distributed over the periphery, the fuel (9) being enriched here with a portion of assisting air

摘要： A combustion chamber with two-stage combustion has primary burners (110) of the premixing type of construction, in which the fuel injected via nozzles (117) is intensively mixed with the combustion air inside a premixing space (130) prior to ignition. The primary burners are of flame-stabilizing design, i.e. they are designed without a mechanical flame retention baffle. They are provided with tangential inflow of the combustion air into the premixing space (130). Arranged downstream of a precombustion chamber (61) are secondary burners (150) which are designed as premixing burners which do not operate by themselves.

摘要： A combustor system for a gas turbine is disclosed in which fuel is mixed with an air stream entering the combustor and is then burned, and the resulting combustion air stream is fed downstream from the combustor to a turbine. A quick and efficient mixing of the air stream and fuel is achieved in that the combustor has an annular diffuser into which the air stream enters. Downstream from the diffuser and communicating with it, at least one essentially annular, toroidal chamber is provided. Mixing pipes extend downstream from the annular, toroidal chamber and are distributed over the periphery of the toroidal chamber. Downstream from the mixing pipes, an annular combustion chamber is provided into which the mixing pipes merge.

摘要： In a gas turbine combustion chamber cooled by means of impingement and convection cooling or pure convection cooling, a compensating flow of the cooling air is guided between adjacent cooling ducts (2) in such a way that the flow velocity in the cooling duct (2) always exceeds a critical limiting value even downstream of a local damage location (6) so that the temperature is less than a critical limiting value. The compensating flow is led past the combustion chamber outer wall. Connecting openings (5) are arranged between adjacent cooling ducts (2) and are respectively offset on the opposite sides of the cooling duct (2).

摘要： A sliding vane engine, where the vanes slide with at least of one of an axial and radial component of vane motion, and where the compression ratio of the engine may be variably controlled. The engine includes a stator and a rotor in relative rotation, and a plurality of vanes in rotor slits defining one or more main chamber cells and one or more vane slit cells. The vanes contain extended pins that move in a pin channel for controlling the sliding motion of the vane. Fuel is mixed by incorporating air turbulence generators at or near the intake region. The intake and exhaust regions of the engine also incorporate a wave pumping mechanism for injecting and scavenging air from the main chamber cells and the vane slits. The compression ratio of the engine may be varied while the engine is in operation, and the engine geometry provides for an extended temporal duration at about peak compression. The engine is insulated by using segmented ceramic inserts on the stator and rotor surfaces.
