Abstract
A reciprocable soot blower that is adapted to extend laterally through an outer wall to remove deposits of slag that collect on the walls of a pressurized furnace, gasifier or other reactor. The soot blower is telescopically mounted in a conduit attached to an outside wall of the furnace to permit its complete withdrawal from the furnace when not in use. A steam seal is adapted to be activated in the conduit when the soot blower is extended to increase pressure in the conduit to thus prevent entry of foreign material from said furnace into the space between the conduit and the soot blower.
