Gas turbine engine combustion chamber having premixed homogeneous combustion followed by catalytic combustion and a method of operation thereof |
摘要 |
A gas turbine engine combustion chamber comprises a primary combustion zone and a secondary combustion zone downstream of the primary combustion zone. A catalytic combustion zone is arranged downstream of the secondary combustion zone and a homogeneous combustion zone is arranged downstream of the catalytic combustion zone. A pilot injector supplies fuel into the primary combustion zone. At least one primary premixing duct has a plurality of primary fuel injectors to supply a first mixture of fuel and air into the primary combustion zone. A secondary premixing duct has a plurality of secondary fuel injectors to supply a second mixture of fuel and air into the secondary combustion zone. A plurality of temperature sensors are arranged at the intake to the catalytic combustion zone and a processor controls the valves which adjust the supply of fuel the fuel injectors to ensure that the temperature at the intake to the catalytic combustion zone remains in a predetermined temperature range.
