Abstract

See full text

A system for changing a bias level of a flame sensing circuit to identify leakage in the flame sensing circuit. The bias level may be varied in the positive or negative axis and the flame current may be noted to identify leakage. The bias level may be changed by a microcontroller. The bias level may be changed using an operational amplifier configuration which is used as a signal conditioner for interfacing the flame signal to the microcontroller.
