Abstract
Hybrid solar-biofuel turbines are very interesting from the economic and environmental point of view, thus many researches are being performed in the field, as well as implemented in industries over the last years. The aim of the present work is to analyze the performance of a solar hybrid micro gas turbine in different cycle configurations. The microturbine simulated was the Capstone C30, which is a recuperative gas turbine engine that operates with natural gas in standard condition. To simulate specific operational conditions, it was used the software GateCycle 6.1.2, using ethanol or natural gas as fuel, simulating a solar energy receiver located either in the high pressure or in the low pressure lines. The results showed a significant gain in thermal efficiency as the solar receiver increases the air temperature, particularly when the receiver is located in the high pressure line. Despite the higher net power obtained when using ethanol, the cycle efficiency was higher when using natural gas in all hybrid cases.
