2. Introduction This presentation covers the essential aspects of gas turbine power plants, including their definitions, components, working principles, and applications. It aims to provide a comprehensive understanding of how these power plants operate and their significance in various industries.

3. Gas Turbine Basics 01

4. Definition and Components Gas turbines are internal combustion engines that convert gas fuel into mechanical energy, typically used for electricity generation or propulsion. Key components include the compressor, combustion chamber, and turbine. The compressor draws in air and pressurizes it, while the combustion chamber mixes the air with fuel and ignites it, causing high-pressure gas to expand and spin the turbine, which generates power.

5. Working Principle The gas turbine operates on the Brayton cycle, which involves four processes: compression, combustion, expansion, and exhaust. Ambient air is compressed to high pressure, then mixed with fuel and combusted to produce hot gases. The high-pressure gas expands through the turbine, generating mechanical energy as it drives the turbine blades. Finally, the exhaust gases are expelled, completing the cycle and allowing continuous operation as long as fuel is supplied.

6. Types of Gas Turbines Gas turbines can be categorized into several types based on their design and application. The main types include: - **Open-Cycle Gas Turbines (OCGT):** These systems operate in a simple cycle without recovering exhaust heat for additional energy. They are commonly used for quick-start peaking power generation. - **Combined-Cycle Gas Turbines (CCGT):** These utilize both gas turbines and steam turbines, capturing waste heat from the gas turbine to generate additional electricity through a steam cycle, improving efficiency. - **Heavy-Duty Gas Turbines:** Designed for base-load power generation, they offer high reliability and fuel efficiency, often seen in large power plants. - **Aero-Derivative Gas Turbines:** Smaller and designed for off-shore and mobile applications, these turbines repurpose aircraft engine technology for power generation.

8. Power Generation Gas turbines are a vital component in electricity generation, especially for rapid response needs and peak power demands. They are favored for their ability to start quickly and efficiently support grid stability. Modern power plants utilize combined-cycle gas turbine systems, which improve overall efficiency by harnessing waste heat for additional electricity production. The flexibility of gas turbines allows them to adapt to varying load demands, making them an essential technology for transitioning to renewable energy sources.

9. Aerospace Industry In the aerospace sector, gas turbines are primarily used in jet engines for both commercial and military aircraft. They provide the necessary thrust for flight by converting fuel into mechanical energy. Aerospace gas turbines are built for high efficiency, lightweight designs, and reliability, which are critical in aviation. Innovations in turbine design often focus on increasing fuel efficiency and reducing emissions, causing the aerospace industry to adopt advanced materials and cooling technologies to enhance performance.

10. Industrial Uses Gas turbines serve various industrial applications across sectors such as oil and gas, marine propulsion, and cogeneration systems. In oil and gas, they are used to drive compressors and pumps, enabling production and processing of fuels. In marine applications, gas turbines power large vessels and ships, providing efficient propulsion at high speeds. Additionally, in cogeneration setups, gas turbines generate electricity while utilizing waste heat for heating processes, significantly improving overall energy efficiency in industrial operations.

11. Conclusions Gas turbines play a pivotal role in modern energy generation and various industrial applications. Their ability to efficiently convert fuel into electricity, adapt to changing demands, and contribute to aerospace technology highlights their versatility and importance. As the industry shifts towards more sustainable energy solutions, advancements in gas turbine technology continue to enhance performance, reduce emissions, and increase efficiency in power generation and beyond.
