Abstract
A process for blast cleaning a surface with a blast media which is softer and more friable than sand such as sodium bicarbonate is provided and which comprises passing the blast media in pressurized air through a blast nozzle including an inlet section which contains a passageway which converges substantially along only one direction to a rectangular venturi orifice and a fan-shaped outlet section which contains a passageway which diverges along substantially only one direction perpendicular to the direction of convergence of the converging passageway, the inlet passageway being greater than twice the diameter of the inlet of the nozzle so as to provide streamlined flow and reduce turbulent flow of the friable blast media in the blast nozzle.
