Abstract

In this paper, the performance analysis of a solar-biogas hybrid recuperator micro gas turbine is presented. The primary objective of this study is to analyze the system energy flow and the solar share effects on the system performance. Moreover, the hybridization of solar gas turbine for power production is examined and the performance of the system with respect to variation of solar share is evaluated. The net output power of the micro gas turbine is fixed at 100 kW. The biogas used for this study is assumed to consist of 80% CH4 and 20% CO2. Brayton cycle with recuperator system performance has been analyzed using Aspen-HYSYS. The solar unit was modeled and simulated by using a block heater in Aspen-HYSYS with direct normal irradiation (DNI) as an input data. The results reveal that by the increase of solar share and hybridization, there is a significant reduction on the CO2 emission and fuel consumption. Moreover, the results show that the heat input from the solar unit and combustion chamber to the system was constant and this led to the system stabilization.
