论文已在中国上海举行的2013年CIMAC大会上发表。论文的版权归CIMAC所有。Against a background of recent energy issues, demand of more efficient operation for power plants typified by the distribution of power plants involving the smart-grid concept are growing, meanwhile the use of shale gas as well as the extension for gas pipeline has been steadily progressing. Therefore, gas engine market is, definitely, expected to grow at a steady pace. Gas engine power generation has a lot of characteristics : High environmental performance, high thermal efficiency, high quick-start and load following capability, high exhaust heat recovery.KU30GSI gas engine has already realize the superior utilization for exhaust energy and cooling energy,like as steam, hot and cold water, and, thus, fulfill the higher efficiency as a cogeneration unit. In addition, its excellent performance for rapid starting potential makes it possible to apply to the backup for renewable energy powers. Mitsubishi Heavy Industries,Ltd.(MHI) has already receive an order of KU30GSI over 30 sets from its release, and requests from many clients regarding the consideration for the introduction of KU30GSI with the favorable feedback about its reliability based on the abundant track record. To cater to the recent demand from the customer more focusing on the power generation, MHI has complete the work for its efficiency increase, and achieve the excellent efficiency of 48.8% (ISO 3 046). The thermal efficiency improvement is an important item which not only lowers the operation cost, but also leads to environmental load reduction and energy saving. Enhancement for Miller cycle, high efficiency turbo charger MET-MB and optimization for combustion chamber aiming fast burn concept contribute to fulfill this efficiency improvement, which was thoroughly evaluated through the test engine verification. Three engines applied to this high efficiency specification were already delivered and have been in successful operation. This paper describes the features and technologies, including the latest development for this efficiency improvement,of KU30GSI gas engine as well as the operation result on actual site.
