| Abstract |
As fuel costs and environmental impacts assume greater importance to aviation and the transport industry, so does the importance of options for increased energy efficiency and emissions reduction. A Brayton Cycle-based, super classic heat regeneration from a turbofan engine used in commercial airplane, a gas turbine engine converts in average up to 50 % of the fuel energy into mechanical shaft work. A significant proportion of the rest of energy (approximately 45 %) is wasted through the cooling liquid and the exhaust gases. Thus, it would be possible to regenerate this wasted heat in order to improve the gas turbine engine overall efficiency and reduce the fuel consumption and to improve the greenhouse gas emissions.
A heat regeneration system for an engine having an low pressure turbine, high pressure turbine and exhaust nozzle whereby exhaust gas is expelled, the heat regeneration system comprising a heat regenerator disposed after the combustion chamber and before exhaust, heat regenerator containing a fluid, heat regenerator is further positioned to utilize heat energy before exhaust gas.
This thesis presents the various systems enabling the heat regeneration from aircrafts, vehicles, train, ship and industrial static gas turbine engines. |
