【摘要】

The 1 MW class gas cogeneration system is expected to be spread rapidly in the near future. The objective of this study is to propose and prove a gas engine cogeneration system with high thermal efficiency and reduction in CO2 emission, which can provide a stable power supply as the supplement of unstable renewable green energy power systems like wind power. To realize the improvement in thermal efficiency, research and development of the following four element technologies were carried out by numerical simulations. Based on the results, the evaluation of the element technologies by using a single-cylinder engine has been made. 1. CO2 reduction and the maximum power increase by improving the thermal efficiency. 2. Enhancement of heat supply by increasing the amount of exhaust gas energy. 3. Improvement of the spark plug’s life and reduction of unburned methane emissions by using the low-temperature plasma technology. 4. A flexible operation achieved by stable combustion and the control of thermoelectric ratio.
