Whole Oxygen Fuel Burner, and funcioconjunto Oxygen Fuel Burner, and operation. Methods.

摘要

An oxygen-fuel burner is disclosed wherein the atomizing fluid not only atomizes a liquid fuel, but also functions to cool the burner tip and prevent eddying of the atomized fuel from collecting on the burner tip, which could create undesirable high temperatures upon ignition. Further, oxygen may be utilized as an atomizing fluid in view of the fact that the atomization of the fuel is accomplished so close to the discharge end of the burner and the discharge velocity is maintained at such a high level, that the contact time of the oxy-fuel within the burner is extremely short, thereby precluding preignition within the burner. Further, the oxygen itself also functions to cool the burner tip and prevent preignition or cracking of the liquid fuel in the atomizing chamber. The burner may be utilized with carbon dioxide as an atomizing fluid wherein the burner temperature is thus lowered reducing the amount of NO.sub.x produced, and the spent gases may be recovered and recycled as the atomizing fluid, in view of the fact that such gases are predominantly 1/3CO.sub.2 and 2/3H.sub.2 O.
