Presentationtitle: Thermodynamic Exhaust Heat Recovery Analysis of an Aero-derivative Gas Turbine using a Subcritical Steam Rankine Cycle

Gas turbines are well-known for their high power to weight ratio, significantly low starting – acceleration times, high flexibility and high reliability. However, conventional gas turbines suffer from low thermal efficiencies especially at partial load. As known, aero-derivative gas turbines are used from many navies around the world, mainly as combined propulsion systems, in various types of naval vessels. Hence, one of the most promising technologies nowadays for efficiency improvement of commercial gas turbines is the combination of a conventional gas turbine cycle with a bottoming Rankine cycle constituting thus a so-called “combined cycle”. According to the combined cycle concept, exhaust gas heat is used for steam production in a specially-designed heat exchanger, which is often called heat recovery steam generator (HRSG). High-enthalpy generated steam is then expanded in a turbine producing thus, additional mechanical power. Hence, for the same fuel heating rate in the gas turbine, an increased power output is attained through bottoming Rankine cycle improving thus, the overall efficiency of the combined cycle facility.A diploma thesis in Hellenic Air Force Academy (HAFA) was recently performed investigating more thoroughly the thermodynamic performance of a combined cycle comprised of an aero-derivative gas turbine and a steam Rankine bottoming cycle. Under the aforementioned thesis, a thermodynamic analysis computational model was developed for examining the thermal performance of a subcritical steam Rankine bottoming cycle, which recovers exhaust gas heat from an aero-derivative gas turbine. The operational behavior of the combined cycle was examined at various gas turbine operating loads and also under various ambient conditions i.e. dry bulb air temperatures and humidity ratios using HAFA’s gas turbine training and simulation software. The technical findings of the present study can be proven quite useful to the military-related scientific community working on materializing solutions for seriously improving the efficiency and downplaying the infrared “signature” of gas turbine-propelled transportation units.
