APPARATUS, SYSTEM, AND METHOD TO PROVIDE AIR TO A DOSER INJECTOR NOZZLE

摘要

An apparatus, system, and method are disclosed for providing air to an injector nozzle. An injector nozzle is in fluid communication with a dosing fluid input. An opening substantially circumscribes the injector nozzle. The injector nozzle is directed toward the opening, injecting a fluid from the dosing fluid input through the opening. An injector air output is in fluid communication with an air input port and with the opening. The injector air output is directed toward the opening, injecting air from the air input port through the opening. The injector air output creates a positive air pressure around the injector nozzle.
