System, method, and apparatus for improved cleaning of industrial furnaces

Abstract

A system, method, and apparatus for cleaning deposits in industrial furnaces. An improved fan jet nozzle for air cannon includes either a 4″ or a 6″ inner diameter circular inlet. The nozzle includes a flattening of the inlet on opposed top and bottom side walls converging towards an outlet of the nozzle. The opposed top and bottom sidewalls have convex surface protruding towards the throat of the nozzle. Lateral sidewalls converge towards the outlet of the nozzle. The lateral sidewalls have a slightly concave curvature protruding outwardly from the interior of the nozzle. The outlet may have an arcuate indentation proximal to a centerline of the lateral sidewalls. The improved performance in face area, planar are, and penetration depth permits employment of half the air cannons in an industrial furnace for cleaning while improving cleaning efficiency in the width and depth of cleaning.
