Abstract:
A sealing arrangement for an electrical machine for reducing a gas leakage flow is invented. The sealing arrangement (1) comprises an electrical machine (2) in gas flow (7) connection with a housing (4). The sealing arrangement comprises an insulating fabric (5) comprising a first (9a) and a second (9b) opposing edge regions. The insulating fabric (5) is fitted to cover a gap (6) between the electrical machine (2) and the housing (4). The insulating fabric (5) is configured to stay non-tensioned, and the insulating fabric (5) is attached to the electrical machine (2) and to the housing (4) by means of cover strips (8). The first (9a) and second (9b) edge regions of the insulating fabric (5) comprise a protrusion (10) and the cover strip (8) comprises a space (25) for locking the protrusion (10) at least partially within the cover strip (8).
Abstract:
A power generation plant has two internal combustion engines (ICE) coupled in a compound configuration to operate electrical generators. A first ICE is a piston/cylinder engine producing high temperature and high pressure exhaust. The exhaust is coupled to the combustion air inlet of the second ICE, which is a gas turbine engine. A heat exchanger transfers heat from the exhaust of the first ICE to a bottoming cycle for additional power generation, also reducing the temperature at the turbine engine combustor. The second ICE (the gas turbine) is operated without an intake compressor, relying instead on the high pressure of the first ICE exhaust. The drive shaft of the gas turbine (or an associated generator/motor or a common shaft) operates a multi-stage turbo-compressor at the combustion air intake of the first ICE for improving engine power output without sapping exhaust energy as with a turbocharger.
Abstract:
A mobile refrigeration unit includes a refrigeration system having a plurality of electric motor driven components and an on-board power supply system for generating electric current and supplying the electric current to the plurality of electric motor driven components. The power supply system includes a first generator for generating a first portion of electric power, a second generator for generating a first portion of electric power, a fuel fired engine driving the first generator, and an organic Rankine cycle system driving the second generator. An engine exhaust line connects the fuel-fired engine in exhaust gas flow communication with the organic Rankine system. The unit may also include a storage battery and a power management system.
