<p>A burner nozzle assembly is disclosed for atomizing liquid fuel at lower emission velocities, and comprises an axially extended nozzle body and a nozzle cap mounted forwardly thereon, the nozzle cap and nozzle body cooperating to define a flow reversing fluid path for the liquid fuel, to cause the fuel to move essentially countercurrent to its initial direction of flow, and to the flow of an auxiliary fluid disposed in an outer coaxial conduit. The reversal of flow of the liquid fuel, promotes a collision between it and the auxiliary fluid, to facilitate thorough atomization, without the need for increase in emission velocities, that results in higher fuel consumption and reduced per capita fuel utilization and heat radiation. The nozzle is adapted to operate in a variety of burner assemblies, including conventional burner guns, and is of simple construction.</p> |
