Abstract:
The invention is directed to a process to obtain a compressed gas starting from a starting gas having a lower pressure by performing the following steps: (i) increasing the pressure and temperature of a gas having an intermediate pressure by means of indirect heat exchange against a fluid having a higher temperature to obtain a gas high in pressure and temperature, (ii) obtaining part of the gas high in temperature and pressure as the compressed gas, (iii) using another part of the gas high in temperature and pressure as a driving gas to increase the pressure of the starting gas in one or more stages to obtain the gas having an intermediate pressure for use in step (i). The invention is also directed to a configuration wherein the process can be performed and directed to a process to generate energy using the process.
Abstract:
The invention is directed to a fluid distributing apparatus comprising a fixed part and a rotating part. The fixed part is provided with at least one inlet channel and at least one outlet channel and wherein each inlet and outlet channel has a facing opening facing the rotating part. The rotating part is rotatably positioned relative to the fixed part such that the rotating part can have multiple rotational positions relative to the fixed part, wherein the rotating part is provided with at least a connecting channel having an inlet and outlet opening in the rotating part. The inlet and outlet opening of at least one connecting channel in the rotating part aligns with the facing openings of at least one inlet and outlet channel in the fixed part in at least one rotational position and not align in another position.
Abstract:
A gas turbine engine includes a gas generator having a compressor, a first turbine member, and a combustor member between the compressor and the first turbine member for increasing the temperature of the fluid medium to be worked upon by the engine. A second turbine is located adjacent to the gas generator and it extracts energy from the fluid medium to produce rotary power. A heat scavenging member is located adjacent to the gas generator for extracting heat from the fluid medium after flowing from said second turbine and for transferring the heat into the fluid medium exiting the compressor by passing the fluid medium at least two times through the scavenging member to heat the fluid medium before flowing into the combustor member.
Abstract:
A low stiffness elastomer mounting arrangement for a ceramic regenerator core comprising an elastomer cushion between a ceramic, circular regenerator core and a surrounding ring gear, portions of the elastomer being bonded to the interior surface of the ring gear and other portions of the elastomer being bonded to the outer periphery of the ceramic regenerator core, the location of the bonds between the elastomer and the ring gear being tangentially offset with respect to the location of the bonds between the elastomer and the regenerator core, adjacent bonds on the ring gear and on the periphery of the regenerator core being tangentially spaced one with respect to the other, the elastomer forming a load transmitting beam construction that is not bonded to either the ring gear or the core whereby driving forces are transmitted from the ring gear to the core while the elastomer compensates for differential expansion of the ceramic core and the ring gear thus avoiding radial stresses and compression loads on the ceramic core.
Abstract:
A compact single shaft gas turbine engine includes a radial compressor and a radial turbine mounted for rotation about a central axis and an axially inline disk regenerator disposed forward of the turbine. A highly efficient engine configuration minimizes energy loss along an improved gas flow path while permitting the engine to be mounted on a standard 22 inch wide farming tractor frame. Efficiency is further increased by a radial exhaust diffuser disposed between the regenerator and turbine which does not contribute substantially to engine size.
Abstract:
A heat input device for a heat engine comprises a combustion device which is adapted to support surface burning of a fuel and oxidant mixture and a heat exchanger which is adapted to transfer the heat from the hot surface against which the surface burning takes place to the working fluid of the engine.
Abstract:
A rotary storage heat exchanger structure for multi-shaft gas turbines, especially motor vehicle gas turbines. The same is arranged in a housing and is provided with one or more rotatable disc-shaped storage bodies having flow passages which extend substantially parallel to the axis of rotation of the storage body or bodies. There are hot exhaust gases and colder compressed working air passed through the passages. The storage body or each of the storage bodies is journaled in a housing web in an overhung position or is journaled at two bearing areas in a housing web or in a housing web and another structural part of the gas turbine. In spaced relationship to the storage body, nozzle gap means are provided on or in the housing in the extended plane separating the working air flow and exhaust gas flow play is provided between the storage body and the pertaining housing web and the inner working air and exhaust gas flow conducting devices.
Abstract:
A three part seal assembly for sealing the rotatable disk regenerator of a gas turbine engine is disclosed. Each part of the seal assembly generally includes a base having one side carrying low friction means for engaging the regenerator and another side carrying a spring mechanism for making sealing contact with a surface on the engine housing and urging the low friction means into sealing engagement with the regenerator. One part of the seal assembly is in the form of a linear crossbar having a spring mechanism including generally parallel, longitudinally extending spring and retainer members. Each of these members has a first portion affixed to the base and a second portion extending away from the base in cantilever fashion. The cantilevered, second portions of the spring and retainer members are in parallel, spaced-apart relation. A relatively thin, resilient, floating sealing element is loosely constrained between the second portions of the spring and retainer, the sealing element having a sealing edge extending beyond the spring and retainer for sealing engagement with the engine housing. This floating seal arrangement avoids crimping or rippling of the resilient seal element under forces produced by the high temperatures and pressures present during engine operation thereby maintaining the integrity of the seal.
Abstract:
Fuel slinger combustor, regenerative air-cooled gas turbine engine embodying the same, characterized by a pre-mix chamber in which fuel is well atomized by being projected against an impingement ring and further atomized and intimately mixed by the shearing action of cool unregenerated opposing swirling air. The remaining primary air also not heated by the regenerator enters through swirl louvres or ports which maintains the fuel-air mixture in a high recirculation state for clean and stable combustion at very lean mixtures. High pressure fuel is fed to the slinger by a high pressure fuel bearing-pump that makes possible starting the combustion at low speeds and at high altitudes.
Abstract:
A seal system for a rotary regenerator with a circular ceramic regenerator core, the seal system including a peripheral portion sealingly engaged with the margin of the core and a cross arm portion extending generally diametrically across the surface of the core, the peripheral seal portions on the cross arm portion being located in seal recesses formed in the gas turbine housing during the casting of the housing thereby forming a portion of the housing assembly, the seal portions being made in segments whereby provision is made for reducing or eliminating seal breakage and maintenance cost.
