A high efficiency method for atomizing a liquid fuel. A liquid fuel is caused to flow into and through a pre-atomization chamber. A first portion of a pressurized atomizing fluid is introduced into the liquid fuel flowing through the chamber so as to at least partially atomize the fuel and provide a first admixture containing atomized fuel and atomizing fluid. The first admixture is delivered from the chamber and caused to flow into and through a first elongated port in an atomizing tip connected to the chamber. A second portion of pressurized atomizing fluid is directed into and caused to flow through a second elongated port in the tip. The first admixture from the first port is introduced into the second port and caused to become intimately intermixed with the second portion of pressurized atomizing fluid so as to further atomize the fuel and provide a second admixture comprising atomized fuel and atomizing fluid. The second admixture is then discharged from the tip as a fully atomized fuel and fluid mixture.

High efficiency method for atomizing a liquid fuel

A high efficiency liquid fuel atomizer includes an elongated generally tubular member defining a liquid fuel pre-atomization chamber. The tubular member has an outer wall that extends around the chamber, an upstream end adapted for connection to a source of liquid fuel and a downstream fuel delivery outlet. The atomizer also includes a larger diameter outer tube that is concentric to the tubular member and defines a generally annular pressurized atomizing fluid supply conduit disposed in surrounding relationship relative to the chamber. The outer tube has an inlet adapted for connection to a source of pressurized atomizing fluid and a downstream pressurized atomizing fluid delivery outlet. One or more orifices are provided in the outer wall of the tubular member so as to intercommunicate the chamber and the annular conduit to permit pressurized atomizing fluid to enter the chamber and at least partially atomize the fluid fuel therein. Also disclosed is an atomizing tip which includes a novel y-shaped for further atomizing the liquid fuel.

High efficiency fuel oil atomizer

Low NO apparatus and methods for burning liquid and gaseous fuels are provided by the present invention. The apparatus of the invention is basically comprised of a housing having an open discharge end attached to a furnace space, means for introducing a controlled quantity of air into the housing and into the furnace space, a combustion compartment disposed within the housing for providing a primary combustion zone therein having an open inlet end for receiving a portion of the air introduced into the housing and an open discharge end, a liquid fuel nozzle attached to the housing for discharging liquid fuel into the primary combustion zone, at least one primary gaseous fuel nozzle for discharging primary gaseous fuel into the primary combustion zone and at least one secondary gaseous fuel nozzle for discharging secondary gaseous fuel into the furnace space.
