Abstract: A nitrogen sweep stream for use in a deaerator during deaerator operations to disperse and remove oxygen and carbon dioxide from boiler feed water prior to being fed to a boiler. The nitrogen sweep stream substantially reduces the amount of oxygen and carbon dioxide in the water supply system. The water supply system can be sent to a deaerator stripper or can be heated using a heat exchanger. A heat water supply stream can also be sent directly to the deaerator water tank. The nitrogen sweep stream reduces the amount of oxygen contained with the boiler feed water stream to less than 7 ppb and reduces the amount of carbon dioxide to nondetectable levels. The nitrogen sweep may be provided to an existing deaerator, not having been previously provided with a nitrogen sweep, while the deaerator is running without shutting down the deaerator.

Abstract: An apparatus and method is presented for reducing mono nitrogen oxide emissions in a hydrocarbon processing furnace. A preferred embodiment hydrocarbon cracking furnace includes a firebox with a set of wall burners and a set of floor burners, the floor burners comprising secondary burner tips burning a fuel-rich mixture and positioned below primary burner tips burning a fuel-lean mixture. A portion of flue gases are recirculated from the primary burner combustion area to the secondary burner combustion area and back to the primary burner combustion area. The floor burners further comprise a set of steam injection ports that inject steam into a conical flow to contact flames at the primary burner tips, reducing flame temperature and thereby reducing thermal NOx. The steam injection ports are positioned in the firebox above the primary burner tips.
