Abstract
A fired heater has two types of burners. The first burner is located in a duct which provides oxygen-containing gas to the heater to be combusted with the fuel provided by the burner. The second burner is located in the heater and provides both air and fuel for combustion. The heater may be located downstream of a gas turbine engine that cogenerates electricity and provides the oxygen-containing gas.
