ABSTRACT:
A combustor with a flashback arresting system for producing a hot gas by burning premixed fuel and compressed air having fuel/air premixing passages, each of the passages having an inlet end and a discharge end. Disposed immediately upstream of the inlet ends of the fuel/air premixing passages is a fuel manifold for delivering fuel to the passages. Fuel lines with fuel flow control valves connect the fuel manifold with a fuel supply. The flashback arresting system has one or more optical flame detectors with a light receiving portion located upstream of the discharge ends of the fuel/air premixing passages and oriented toward at least a portion of at least one of the fuel/air passages. The flame detectors are responsive to receiving light from a flashback by its light receiving portion by transmitting an output signal to a control system. The control system controls the fuel flow control valves and responds to the output signal by adjusting the fuel flow control valves to eliminate the flashback.
