Gas turbines are essential in industrial applications due to their ability to handle peak loads efficiently, making them crucial in power generation and the oil and gas industry. They are commonly used in combined heat and power (CHP) plants, cogeneration systems, and as mechanical drives for pumps, compressors, and generators. Their operation involves compressing air, mixing it with fuel in a combustion chamber, and expanding the resulting hot gases through a turbine to generate mechanical energy, which can be converted into electricity or used for heating. Gas turbines run on various fuels, including natural gas and diesel, and optimizing their efficiency requires precise control of combustion settings and exhaust gas parameters. Monitoring emissions like CO and NOx is vital for maintaining performance and adhering to environmental regulations. Operational challenges include managing gas concentrations during startup, reducing NO₂ emissions, and minimizing pressure losses, all of which are critical for efficient and low-emission performance.
