摘要: This disclosure relates to a highly efficient gas turbine engine architecture utilizing multiple stages of intercooling and reheat, ceramic technology, turbocharger technology and high pressure combustion. The approach includes utilizing a conventional dry low NOx combustor for the main combustor and thermal reactors for the reheat apparatuses. In a first configuration, there are three separate turbo-compressor spools and a free power turbine spool. In a second configuration, there are three separate turbo-compressor spools but no free power spool. In a third configuration, all the compressors and turbines are on a single shaft. Each of these configurations can include two stages of intercooling, two stages of reheat and a recuperator to preheat the working fluid before it enters the main combustor.

摘要: Various embodiments are disclosed to utilize various fuels, including liquid natural gas fuels, to improve engine efficiency in gas turbine engines. In one configuration, a fuel is heated by a heat exchanger utilizing waste exhaust heat of a gas turbine engine. In another configuration, LNG fuel is heated using a pre-cooler for the inlet air stream of a gas turbine engine. In another configuration, fuel is injected into the pressurized air, downstream of the air-to-air intercooler. In yet another configuration, fuel is pumped through the engine's intercooler or a secondary heat exchanger exchanging heat with the compressed air stream between the low-pressure compressor and high-pressure compressor. In another configuration, the fuel is first heated by the intercooler and then further heated by a heat exchanger utilizing waste exhaust heat of the gas turbine engine.

摘要: A closed-loop organic Rankine cycle apparatus to extract waste heat from the exhaust gas from a gas turbine engine is disclosed wherein the closed loop includes at least one additional heat exchanger. An additional heat exchanger for heating fuel may be in one of three locations relative to the ORC turbine and condensing heat exchanger. One location is a preferred location for adding heat to all fuels (liquid, gaseous and/or cryogenic). Another location is a practical location for adding heat to very cold or cryogenic fuels such as CNG or LNG. The closed-loop organic Rankine cycle apparatus, besides extracting waste heat from the exhaust gases, may also include an additional heat exchanger to recover heat from a compressor on a gas turbine engine prior to entering an intercooler on a gas turbine engine.In another embodiment, the exhaust stream can be directed, in selected proportions, to a closed organic Rankine cycle, a heat exchanger for pre-heating fuel or directly out an exhaust stack.
