Abstract
A method for use in evaluating an operation of a combustion machine. A plurality of current average intensities is calculated by a computing device based on a series of intensity readings from a flame sensor. Each current average intensity corresponds to a current time interval. The computing device selects a plurality of past average intensities, each of which corresponds to a past time interval equal in duration to the current time interval corresponding to a current average intensity. The computing device calculates a plurality of decay rates indicating a change in intensity readings over a current time interval based on the current average intensities and the past average intensities. The computing device estimates a predicted flame sensor malfunction time based on the plurality of decay rates.
