Abstract
The control of the flow rates of multiple fuel streams to furnace burners is accomplished by manipulating the flow rate of each fuel stream in response to a calculation of the heat duty which must be supplied by the respective fuel stream. Where the supply of a preferred fuel is variable, the flow rate of the other less preferred fuel stream is varied in response to changes in available supply of the preferred fuel to insure that sufficient fuel is available to the burners to maintain a required process temperature.
