Abstract
A burner apparatus is operated in a plurality of distinct modes. In a startup mode, flows of oxidant and primary fuel are ignited by an igniter and are provided simultaneously with a flow of secondary fuel until a process chamber reaches the auto-ignition temperature of the secondary fuel. In a subsequent mode, flows of oxidant and secondary fuel are provided simultaneously to the exclusion of a flow of primary fuel.
