Abstract
A flame retention head for a nozzle block assembly of a waste oil-burning system, such as a furnace, having a combustion zone within which oil is burned in the presence of air utilizes a platen-like body of substantially circular form having a central opening through which an atomizing nozzle is positioned for directing air and oil into the combustion zone for burning. The central opening has a diameter of no less than about 1.3 inches, and the platen-like body including a plurality of radially-extending vanes formed therein wherein each vane forms with the remainder of the platen-like body a gap which is joined to and extends radially-outwardly of the central opening. Each gap formed by a vane has a width which is no less than about 0.07 inches. Associated with the nozzle block assembly is at least one air vane for balancing the air flow moving past the flame retention head and toward the combustion zone. When oil and air are directed into the combustion zone for burning, the retention head ensures that the resulting burn is complete so that relatively few hydrocarbons, if at all, are left unburned.
