Zusammenfassung:A method for heating reactor using a multi-function burner comprising feeding primary fuel through an annular channel, feeding oxygen through a central channel within the annular channel, and feeding an auxiliary fuel through a central lance within the central channel to produce a flame extending into a furnace having a temperature and a pressure; wherein the flow rate of the auxiliary fuel and oxygen are increased while maintaining an equivalence ratio below 1 to increase the temperature of the furnace; wherein after the furnace temperature exceeds the auto-ignition temperature of the primary fuel, increasing the flow rate of the primary fuel to increase the equivalence ratio to be greater than 1.
