Krushnevich S. Research of energetic efficiency of gas turbine thermal cycles of gas transport system of Ukraine

The study is to determine the loss in thermal cycles GT and develop ways to improve their effectiveness. The practical significance of the results: The results of the thesis are intended for use in design practice of the heat-GT at different cycles and express analysis of the effectiveness of existing facilities and choice of main areas of improvement.The proposed solution to improve power cycle "Aquarius" by 5.4%. A solution to improve the efficiency of existing and new gas turbine by using differential pressure between the gas turbine combustion chamber and gas mains. The results of comparison of the specific robotozdatnosti low boiling working bodies that can make the best selection of low boiling working fluid depending on the temperature of the beginning of the cycle of secondary disposal path. The results are used on "Zorya-Mashproekt" in studies of the efficiency of gas turbine installations of complex thermodynamic cycles and identifying key areas for improvement. Also, results were used to develop proposals on Ukraine's GT modernization and use of secondary heat gas turbine installations. Industries: engineering, gas turbine, gas transportation system.
