Abstract: A flame responsive system includes a flame sensor, flame signal generating circuitry responsive to the flame sensor and flame signal inhibiting circuitry also responsive to the flame sensor. A fast filter and a slower filter are coordinated so that total loss of flame sensor response results in rapid termination of a flame signal output from the flame signal generating circuitry while reduction of a flame sensor response below a set point causes the flame signal inhibiting circuitry to inhibit the flame signal output.

Abstract: A flame monitoring system includes a flame sensor for producing a flame signal as a function of flame conditions in a monitored environment and flame signal enhancing circuitry coupled to the flame sensor. The flame signal enhancing circuitry has a first response as a function of a first characteristic of the flame signal and a second response different from the first response as a function of a second characteristic of the flame signal and is arranged to combine the first and second responses to provide an enhanced flame signal representative of the monitored flame.
