Although it is known to improve the efficiency of combustion by feeding steam into an open flame, the present invention achieves an extraordinary increase in efficiency by feeding steam from the vicinity of the burner directly into the flame at a controlled rate such that the steam exceeds 15% (and preferably is 60% to 90%) of the oxygen theoretically required for complete combustion, but less than the rate at which the flame would be extinguished. |
