A high efficiency cogeneration system (CGS) is proposed for utilizing high temperature exhaust gas (HTEG) from a gas engine (GE). In the proposed system, for making use of heat energy of HTEG, H₂O turbine (HTb) is incorporated and steam produced by utilizing HTEG is used as working fluid of HTb. HTb exhaust gas is also utilized for increasing power output and for satisfying heat demand in the proposed system. Both of the thermodynamic characteristics of the proposed system and a gas engine CGS (GE-CGS) constructed by using the original GE are estimated. Energy saving characteristics and CO₂ reduction effects of the proposed CGS and the GE-CGS are also investigated. It was estimated that the net generated power of the proposed CGS has been increasd 25.5% and net power generation efficiency 6.7%, compared with the the original GE-CGS. It was also shown that the proposed CGS could save 27.0% of energy comsumption and reduce 1137 t-CO₂/y, 1.41 times larger than those of GE-CGS, when a case syudy was set and investigated. Improvements of performance by increasing turbine inlet temperature were also investigated.
