Flame control in furnace burners has previously lacked any means for sensing the position of the apex of the combustion with respect to the entry throat of the burner. This has resulted in inefficient combustion and, in certain cases, explosions resulting from the fact that the flame may be extinguished during operation of the burner. This invention provides a simple and effective apparatus for detecting and locating the apex of the burner flame within the throat of the combustion chamber. The flame sensing means is adapted to detect the position of the apex of the flame with respect to the throat of the burner and control means is provided which is responsive to the flame sensing means for controlling the forward velocity of the air admitted.
