Exergy analysis and performance of a tug boat power generator using kerosene fuel blended with aspire methly ester

Stringent emission rules, air pollution, fluctuation of fuel price and depletion of fossil fuel resources are driving the industry to seek for better alternative of power generation. Micro gas turbine (MGT) provides a promising potential to solve the facing problems. MGT could be used in many applications such as in range extender vehicle, auxiliary power generator, power backup system, combine heat and power system, etc. Combustor plays a very crucial role in MGT system as its performance directly affects the emission quality, power output and fuel consumption of the entire system. This paper demonstrates the literature review, design methodology and performance prediction of the combustor designed for a 14.5kW MGT test rig.

This work presents an exergy analysis and performance assessment of three recuperative thermodynamic cycles for gas turbine applications. The first configuration is the conventional recuperative (CR) cycle in which a heat exchanger is placed after the power turbine (PT). In the second configuration, referred as alternative recuperative (AR) cycle, a heat exchanger is placed between the high pressure and the PT, while in the third configuration, referred as staged heat recovery (SHR) cycle, two heat exchangers are employed, the primary one between the high and PTs and the secondary at the exhaust, downstream the PT. The first part of this work is focused on a detailed exergetic analysis on conceptual gas turbine cycles for a wide range of heat exchanger performance parameters. The second part focuses on the implementation of recuperative cycles in aero engines, focused on the MTU-developed intercooled recuperative aero (IRA) engine concept, which is based on a conventional recuperation approach. Exergy analysis is applied on specifically developed IRA engine derivatives using both alternative and SHR recuperation concepts to quantify energy exploitation and exergy destruction per cycle and component, showing the amount of exergy that is left unexploited, which should be targeted in future optimization actions.
