Flame holders are devices used in combustion systems, such as gas turbines and jet engines, to stabilize the flame during operation. They help maintain a continuous flame by creating turbulence in the airflow, which mixes fuel and air more effectively. This ensures efficient combustion and prevents the flame from being extinguished. These components are crucial for the performance and safety of engines. By optimizing the combustion process, flame holders contribute to better fuel efficiency and reduced emissions. They are often designed in various shapes and sizes to suit different engine types and operational conditions, enhancing overall engine reliability.
