| Abstract | ||
| Exhaust gases of gas turbine generators contain a significant amount of thermal energy which can be recovered externally or internally to the cycle itself. The most effective technology option for external heat recovery is the combined gas-steam power plant. The internal recovery conventional solutions are based on thermodynamic regeneration and steam injection. In this study a thermal analysis and performance evaluation has been carried out to investigate the benefit of applying combined cycle power plant on Beijee simple gas turbine generators. Beijee gas turbine generator has been modeled and simulated to observe its performance including power output , thermal efficiency , specific fuel consumption and exhaust gas temperature as it is operating for the time being. Thereafter, simulation was carried out to investigate the performance of the suggested unit when a combined cycle power plant is used. Results show that a significant improvement in the performance of Beigee gas turbine unit when a combined cycle mode is applied. For example the power output is found to be increased nearly by 49.3%, the thermal efficiency increased nearly by 20% and the specific fuel consumption decreased nearly by 10%. | ||
