Osaka Gas and Nagoya University has designed a new gas turbine for a cogeneration system. One of the features of our system is its great energy-effectiveness, especially in power generation. A key technology of our system is a steam injection and a two-stage combustion. Besides that, all of the by-product steam is injected for increasing its power density and its efficiency. However, this technology also creates severe circumstances for stable combustion, because the steam tends to substitute for the intake air and thereby leads to leaner oxygen circumstance. To determine the optimal conditions for stable combustion under such the circumstance, fundamental studies on combustion have been exerted. This paper presents the characteristics of our system and some experimental results concerning the optimal conditions for stable combustion. In addition, the results of case studies that estimate the environmental impact of our system are described.
