Optimization of the Operating Parameters of Steam-Gas Turbines
Abstract
In recent times, interest in the energy sector in our country has been increasing. One of the main reasons for this is that our country's energy potential is showing itself with an increasing graph against the background of investments made by our country in energy production for both domestic consumption and the foreign market. Along with renewable energy sources, interest in traditional energy production areas has increased significantly in recent years. An example of this is the reconstruction of the newly commissioned 1280 MW Azerbaijan Thermal Power Plant and the construction of new power units. Steam-gas plants are important parts of modern energy systems in terms of high profitability, rational use of fuel, and renewal of environmental indicators. The efficiency of the plants depends on the optimality of temperature, pressure, flow, and loading regimes. The inlet temperature of the gas turbine, the compression level (degree), heat exchange in the steam generator, steam parameters, and condensation regime determine the useful work coefficient. In the article, the improvement of regime parameters is studied using thermodynamic and exergy approaches, the main sources of energy and exergy losses are identified, and optimal work areas are formed. Optimized parameters reduce fuel consumption, increase electricity generation, minimize equipment loading, and increase operational reliability, which is of practical importance in terms of increasing energy efficiency and minimizing environmental impact. At the same time, the results obtained make a significant contribution to flexible management of energy systems, ensuring long-term sustainability, reducing maintenance costs, and ensuring stable operation of facilities in an environment of changing load schedules. This approach creates broad opportunities in the modern industrial environment for improving regional energy security and continuously increasing economic efficiency.
