ABSTRACT:
An oxy-burner having a back-up firing system includes an oxidant conduit coupled to an oxidant injector nozzle. A primary oxygen line is coupled to the oxidant conduit and transports oxygen into the oxidant conduit. An auxiliary air ejector is coupled to the oxidant conduit and is configured to receive a motive fluid and to entrain ambient air and force the entrained air into the oxidant conduit. In operation, upon detecting a disruption in the primary oxygen supply, a motive fluid is supplied to the auxiliary air ejector. The motive fluid injected by the auxiliary air ejector entrains ambient air sufficient to either continue operation of the oxy-burner, or provide cooling air to the oxy-burner in the event that the burner is shut down. Upon restoring the primary oxygen supply, the back-up oxy-burner system can be deactivated and the oxy-burner return to standard operation.
