- Abstract
In order to study the operating performance of biomass gas micro-turbine, the micro-turbine model was built. Based on the design data of the C60 micro-turbine, the rationality of the model was verified by using natural gas as fuel firstly. Then with biomass gas as fuel, such as biogas, pine wood gas and dry cow dung gas, under two working conditions of the output power of the units at 60 kW and the outlet flue gas temperature of the combustor at 1 145 K, the main output parameters of the gas turbine were obtained respectively. The results show that when the output power of the gas turbine is maintained at 60 kW, the required biomass gas flow increases, the outlet flue gas temperature of the combustor decreases, the pressure ratio increases, the compressor power consumption decreases, and the unit efficiency increases. When the outlet flue gas temperature of the combustor is maintained at 1 145 K, the fuel flow increases, which results in the increase of flue gas flow, the increase of gas turbine output power, the increase of the unit output power and efficiency. When the initial temperature of fuel rises from 300 K to 700 K, as well as the rated output power is maintained, the thermal efficiency of the units increases with the rise of the initial fuel temperature. When the rated outlet temperature of combustor is maintained, with the rise of the initial fuel temperature, the fuel flow rate, as well as the unit output power and thermal efficiency decreases.
