Abstract
A flame monitoring system for use on the furnace (10) of a vapor generator (2) employing tiltable burners (14) and particularly on a furnace equipped with tilting burners arranged in accord with the tangential firing method. Each burner is provided with its own individual scanner. Each scanner (20) is disposed to sight transversely across the base (30) of the flame (18) emanating from its associated burner (14). A plurality of at least three light transmission tubes (26) are stationarily mounted within each scanner head (24) with at least one tube (26A) mounted to sight at an upward acute angle across the flame, at least one other tube (26B) mounted to sight horizontally across the flame, and at least a third tube (26C) mounted to sight at a downward acute angle across the flame. A separate fire ball scanner (60) is mounted in the waterwall and aimed to sight at the center of the furnace (10) to monitor the fire ball (50) formed therein by the flames (18) emanating from the individual burners (14).
