ABSTRACT:
The efficiency of a furnace is substantially maximized by manipulating the amount of oxygen supplied to the combustion process in the furnace so as to provide a desired oxygen concentration in the flue gas which will result in substantially maximum furnace efficiency. Feed forward control based on the fuel flow rate may also be utilized to enable the control based on oxygen concentration in the flue gas to respond more quickly to a change in the fuel flow rate.
