SYSTEM AND METHOD FOR REAL-TIME MEASUREMENT OF THE WEALTH OF A MIXTURE OF GAS AND FUEL

摘要

Real-time control of a richness of a gas and fuel mixture of a gas turbine engine. The system includes multiple optical probes disposed on a plurality of fuel injectors for emitting laser beams directly through a mixture of gas and fuel or indirectly by reflecting laser beams from a surface of a central body or a laser beam. burner tube of the fuel injector. The system also includes one or more detectors (26) for measuring laser beams emitted from multiple optical probes. In addition, the system includes a data acquisition subsystem (30) for acquiring and processing signals from the at least one sensor (26) to determine the richness of the gas and fuel mixture of the injector.
