Theory indicates regenerative gas turbines should achieve higher thermal efficiencies than those of diesel engines and combined- cycle engines. Further, regenerative gas turbines are potentially lower in cost, require less maintenance, require less space, and pollute less than competitive systems. Regenerators can be used for exhaust-gas heat exchange or for intercooling in gas-turbine systems. As an exhaust-gas heat exchanger, a regenerator recovers heat from the exhaust and uses it to preheat the compressed air before the compressed air enters the combustor. Preheating of the compressed air permits a small heat input to the combustor for a given power output of the engine. As an intercooler, a regenerator cools the gas between compressor stages. Less work is required to compress cool gas than is required to compress warm gas. Therefore, a regenerator intercooler can reduce the required work input to the compressor. Thus, regenerators can be used to increase the thermal efficiencies and power ou | 出版日期 | Book 1996 | 關(guān)鍵詞 | Turbine; design; gas turbine; heat transfer | 版次 | 1 | doi | https://doi.org/10.1007/978-1-4613-1209-3 | isbn_softcover | 978-1-4612-8512-0 | isbn_ebook | 978-1-4613-1209-3 | copyright | Chapman & Hall 1996 |
