Design and production of a mini-turbo reactor and study of its dual-fuel (gas-hydrogen) operation

The objective of this research was to investigate the effects of hydrogen injection on the performance of a mini turbo reactor. To achieve this, an experimental test bench was constructed, incorporating a specially designed mini turbo reactor capable of operating on various fuel mixtures and a dry cell electrolyzer for on-site hydrogen production. A comprehensive testing campaign was conducted, comparing the mini turbo reactor performance when fueled with pure propane and a propane-hydrogen blend at varying concentrations. Parameters evaluated included power output, thermal efficiency, fuel mass flow rate, flame temperatures, and pollutant emissions (CO, CO2, NOx). The experimental results unequivocally demonstrated that the addition of hydrogen to propane significantly enhances the mini turbo reactor specific power while concurrently reducing CO and CO2 emissions. Furthermore, data analysis revealed an improvement in the thermal efficiency of the cycle, suggesting potential reductions in specific fuel consumption. These findings highlight the promising potential of hydrogen injection as a strategy to enhance the performance and environmental impact of mini turbo reactor.
