Abstract
A burner for an exhaust aftertreatment system is provided that includes a nozzle assembly having a body and a heating element. The body may include first and second cavities, a fuel inlet passage and an air inlet passage. The first cavity may receive portion of the heating element and may be in fluid communication with the fuel inlet passage and a fuel discharge passage such that fuel from the fuel inlet passage is heated in the first cavity by the heating element and discharged from the first cavity through the fuel discharge passage. The second cavity may be in fluid communication with the air inlet passage and an air discharge passage. The first and second cavities may be fluidly isolated from each other and may supply fuel and air, respectively, to an exit aperture disposed downstream of the fuel discharge aperture and the air discharge aperture.
