Abstract: A startup burner assembly for a recovery boiler, the startup burner assembly includes a housing having a burner end and a second end distal to the burner end; a main fuel conduit disposed within the housing; and at least one high-pressure air conduit disposed within the burner end of the housing. The high-pressure air conduit includes at least one angled air injection nozzle configured to direct high-pressure air exiting the burner end of the startup burner assembly in a rotational direction.

Abstract: The present disclosure describes an assembly configured to mitigate the harmful effects of smelt fouling, airflow interference, and operator exposure to hot air from the furnace and wind box through use of an extractable startup burner and an isolation chamber engaged to a windbox. The present disclosure also describes a method for safely extracting a startup burner from an active recovery boiler as has method for inserting an extractable startup burner into a recovery boiler during operation.
