1. Apparatus for detecting flame, comprising:

  • a first sensor sensitive to a first region of a characteristic infrared water emission band, said first sensor generating a first signal representative of infrared radiation in said first region;

    a second sensor sensitive to a second region of said characteristic infrared water emission band, said second sensor generating a second signal representative of infrared radiation in said second region;

    a third sensor sensitive to a third region of said characteristic infrared water emission band, said third sensor generating a third signal representative of infrared radiation in said third region;

    a processor in communication with said first, second, and third sensors so as to receive said first, second and third signals;

    said processor generating an alarm signal when said first, second, and third signals are indicative of flame.
