摘要： A shower header type spraying device having an elongated spray header with a plurality of laterally-spaced nozzles and an elongated cleaning brush assembly supported in said spray header for cleaning inlet apertures of said spray nozzles. The cleaning brush assembly includes an axially extending rod and a plurality of brush elements each mounted on the rod by means of a self-aligning member that has an arcuate shape corresponding to the outer circumference of the rod for orienting a row of brush bristles of the brush element in predetermined relation to the elongated axis of the rod. The illustrated brush rod assembly includes a plurality of brush rod segments each having a self-aligning coupling at an axial end thereof such that joining of adjacent rod segments automatically orients the brush elements in predetermined angular offset relation to each other.

摘要： A lance-type spraying assembly for directing a reducing agent into a combustion zone or discharging combustion gases for Nox emission control. The spraying assembly including a lance body having an inlet end and a downstream end and a spray nozzle arranged at the downstream end of the lance body. The lance body includes an air passage for connection to an air supply, a liquid reducing agent supply passage for connection to a liquid reducing agent supply and a liquid reducing agent return passage. The liquid reducing agent supply passage communicates with the spray nozzle. The liquid reducing agent return passage communicates with the liquid reducing agent supply passage near the downstream end of the lance body for recirculating a portion of the liquid reducing agent and extends near the liquid reducing agent supply passage along at least a portion of the length thereof in order to help cool the liquid reducing agent therein. The liquid reducing agent return passage is sealed against the spray nozzle. The air passage extends near at least a portion of the liquid reducing agent supply passage in order to help cool the liquid reducing agent therein.
