#4 Fuel Gas System

Fuel Gas System in a Gas Turbine The fuel gas system is responsible for delivering fuel to the combustion section of a gas turbine. It ensures a steady and reliable supply of fuel, while also managing fuel quality and minimizing emissions. Key Components of the Fuel Gas System: Fuel Storage: The system may include fuel tanks or storage facilities to store the fuel before it is used. Fuel Filters: Filters are used to remove impurities and contaminants from the fuel, preventing them from clogging the fuel injectors or damaging the engine. Fuel Pumps: Pumps are used to transport the fuel from the storage tanks to the combustion section. Fuel Heaters: In cold climates, fuel heaters may be used to warm the fuel to improve its flow properties and prevent fuel gel formation. Fuel Injectors: These devices deliver the fuel into the combustion chamber, ensuring proper mixing with the air. Fuel Control Valves: These valves control the flow of fuel to the combustion section, adjusting the fuel-to-air ratio as needed. Fuel Pressure Regulators: These regulators maintain a constant fuel pressure at the injectors, ensuring consistent fuel delivery. Fuel Gas Conditioning Systems: These systems may be used to remove impurities like sulfur and water from the fuel, improving its quality and reducing emissions. Types of Fuel Gas Systems: Liquid Fuel Systems: These systems are used to deliver liquid fuels such as natural gas condensate or diesel fuel. Gaseous Fuel Systems: These systems are used to deliver gaseous fuels such as natural gas or biogas. Dual Fuel Systems: These systems can handle both liquid and gaseous fuels, providing flexibility in operation. Challenges in Fuel Gas System Design: Fuel Quality: Ensuring that the fuel meets the required specifications in terms of purity, heating value, and other properties is essential. Fuel Supply Reliability: Maintaining a consistent and reliable supply of fuel to the engine is crucial. Emissions Control: Reducing emissions from the fuel gas system, such as NOx and CO2, is a major design challenge. Fuel Flexibility: Designing a system that can handle a variety of fuels can be complex.
