A
combustor is a component or area of a
gas turbine,
ramjet, or
scramjet engine where
combustion takes place. It is also known as a
burner,
combustion chamber or
flame holder. In a gas turbine engine, the
combustor or
combustion chamber is fed high pressure air by the compression system. The combustor then heats this air at constant pressure. After heating, air passes from the combustor through the nozzle guide vanes to the turbine. In the case of a ramjet or scramjet engines, the air is directly fed to the nozzle.
