ABSTRACT:
Disclosed is an air-assisted simplex spray nozzle assembly for a fuel burner that includes, inter alia, a nozzle body that has opposed upstream and downstream ends, wherein the downstream end of the nozzle body defines a fuel outlet, an adapter member that is engaged with the upstream end of the nozzle body and defines concentrically positioned air and fuel inlets for the nozzle assembly and an air cap that is positioned over the downstream end of the nozzle body. The nozzle assembly further includes a fuel circuit and a first air circuit. The fuel circuit directs fuel from a fuel pump toward the fuel outlet of the nozzle body. The fuel circuit extends from the fuel inlet of the adapter member through the nozzle body to the fuel outlet. The first air circuit directs assist air towards the fuel exiting from the fuel outlet. The first air circuit extends from the air inlet of the adapter member, through a gap defined between the air cap and the nozzle body and merges with the fuel emitted from the fuel outlet of the nozzle body. In certain embodiments, the assist air is provided to the first air circuit by an auxiliary pump.
