Abstract
Gas turbines play a pivotal role in aviation, power generation, and industrial applications, necessitating continuous advancements in combustion technology to enhance performance and reduce environmental impact. This paper provides a comprehensive analysis of gas turbine combustion systems, covering diffuser aerodynamics, combustor configurations, flame stabilization mechanisms, and fuel injection techniques. Various diffuser geometries, including faired, dump, and vortex-controlled designs, are examined for their impact on flow stability and pressure recovery. The study further explores primary combustion chamber configurationsannular, can, and can-annularhighlighting their efficiency, maintenance considerations, and fuel-air mixing characteristics. Additionally, lean-premixed (LPM), rich-quench-lean (RQL), and trapped vortex combustion (TVC) strategies are discussed in the context of low-emission gas turbine operation. The paper also investigates catalytic combustion, fuel atomization processes, and emissions control technologies, including selective catalytic reduction (SCR) and water injection for NOx mitigation. With increasing emphasis on alternative fuels such as hydrogen, syngas, and biofuels, the study evaluates their combustion behavior and feasibility for future gas turbine applications. The findings suggest that integrated combustion design improvements, coupled with advanced fuel injection and emissions control strategies, are critical for achieving high efficiency, stable operation, and reduced environmental footprint in next-generation gas turbines.
