A detector for use in a combustion system includes a probe having a tip adapted for placement through a singular aperture in the mixing area of a combustion system. First and second channels are derived from the probe output and are used to detect a flashback or flameout condition.
[ What is claimed is:] [1.] A detector for use in a combustion system having a mixing area for fuel and air upstream of a combustion chamber, wherein the combustion system includes means for providing fuel and air to the mixing area and means for igniting the fuel and air in the combustion chamber l
[ What is claimed is:] [1.] A detector for use in a combustion system having a mixing area for fuel and air upstream of a combustion chamber, wherein the combustion system includes means for providing fuel and air to the mixing area and means for igniting the fuel and air in the combustion chamber located downstream of the mixing area, the detector comprising:a probe having a tip adapted for placement proximate the mixing area and having an optical sensitivity to radiation present in both the mixing area and the combustion chamber and responsively providing an optical output related to such radiation;a first channel having a first channel signal derived from an optical probe output, the first channel including a first comparator which compares the first channel signal to a first channel threshold and responsively provides a first channel output related to a flameout condition in the combustion system; anda second channel having a second channel signal derived from the optical probe output, the second channel including a second channel comparator which compares the second channel signal to a second channel threshold and responsively provides a second channel output related to a flashback condition in the combustion system.
