Abstract

Natural gas engine (Wartsila 18VSG) having meanly 5993 kW electrical power output and used in a Trigeneration system located in Ankara was analyzed in terms of energy and exergy. Analysis, which is used actual data, was made to natural gas engine, heat recovery boiler and absorption chiller, while trigeneration system on full load operation conditions. Energy loss, energy efficiency, exergy destruction and exergy efficiencies of the trigeneration system was calculated. The energy and exergy efficiencies of system were determined as 64 % and 39 % respectively. FESR (fuel energy saving ratio) and FESxR (fuel exergy saving ratio) were calculated as % 27, % 28 respectively for Trigeneration facility.
