内容記述 |
A small-scale prime mover especially micro gas turbine is a key factor in order to widespread the utilization of biogas. It is well known that a performance of large-scale gas turbine is greatly affected by its inlet air temperature. However, the effect of the inlet air temperature on the performance of small-scale gas turbine (micro gas turbine) is not widely reported. The purpose of the present study is to investigate the effect of the inlet air temperature on the performance of a micro gas turbine (MGT) with cogeneration system (CGS) arrangement. An analysis model of the MGT-CGS was set up on the basis of experimental results obtained in a previous study and a manufacturer standard data, and it was analysed under a various ambient temperature condition in a cold region. The results show that when ambient temperature increased, electrical efficiency η_<ele> of the MGT decreased but exhaust heat recovery η_<ehr> increased. It was also found that when ambient temperature increased, exhaust heat to mass flow rate Q_<exe>/m_e and exhaust heat recovery to mass flow rate Q_<ehr>/m_e increased, with maximum ratios of 259 kJ/kg and 200 kJ/kg, respectively were found in summer peak. Furthermore, it was also found that the exhaust heat to power ratio Q_<exe>/P_e had a similar characteristic with exhaust heat recovery to power ratio Q_<ehr>/P_e. Q_<exe>/P_e and Q_<ehr>/P_e increased with the increase of ambient temperature. Moreover, although different values of total energy efficiency, fuel energy saving and CO_2 reduction for every temperature condition were found comparing with a two conventional system that were considered, the MGT-CGS could annually reduce 30,000-80,000 m^3/y of fuel consumption and 35?94 t-CO_2/y of CO_2 emissions. |
