ABSTRACT:
Contamination rate reduction for a flame detection or sensor arrangement using controlled but flexible flame sensor activation. A flame sensor of the subject application is subject to contamination which reduces the lifetime of the sensor. To reduce a contamination rate of the flame sensor, the sensor may be inactivated for certain periods of time when the necessity of flame detection does not appear significant for the use at hand.
