Note:
A 4237 kWe gas turbine has been operating for about one year at an agro-food industry in cogeneration application; 15 t/h of 5.0 MPa 410° C steam is there produced. About 400 kW of mechanical energy for the main pump of the steam generator and for a cooling water pump is produced by steam turbines, driven by the steam expansion from 5.0 MPa to 1.2 and 0.5 MPa. Experiences in the first months of operation are discussed. The analysis of the on-site performance test data, recorded from the available station instrumentation, assesses the output power and the heat rate of the plant. The thermoeconomic analysis of the energy-transformation plant has been completed developing a performance evaluation based on a first- law as well as second-law analysis.
