【発明の名称】ガスタービンエンジン用低有害排出物燃焼ノズル
Document Type and Number:
Japanese Patent JPH06510361
Kind Code:
A
Abstract:
The known systems and injector nozzles for reducing NOx in the combustion systems of past gas turbine engines has generally failed to effectively and efficiently reduce the NOx level. The present system reduces the formation of NOx within the combustion zone by controlling the air/fuel ratio and more explicitly by controlling the air portion of the air/fuel ratio. The present injector nozzle includes a device for introducing a primary supply of air through the injector nozzle which is sized to have a predetermined cross-sectional area. The injector nozzle further includes a device for introducing a secondary supply of air through the injector nozzle which is sized to have a predetermined area. A device for introducing a primary supply of air through the injector at a controlled rate and a device for passing a main source of fuel through the injector nozzle at a controlled rate relative to the quantity of primary supply of air. The system with the injector nozzle provides an economical, reliable and effective method for reducing and controlling the amount of nitrogen oxide (NOx), carbon monoxide (CO) and unburned hydrocarbon (UHC) emitted from the gas turbine engine.
