Abstract
A method of monitoring a selected flame in a multi-burner furnace comprises positioning two arrays of photoelectric sensors, providing an optical path for the sensors of each array so that the line of sight of one sensor of one array will intersect the line of sight of one sensor of the other array, electronically scanning the two arrays to determine the sensors, one from each array, which give maximum correlation of output signals from the sensors to electronically optimize the signals generated from selected sensors, and electronically locking on to the selected sensors to monitor the selected flame.
