Abstract
An apparatus is described for cleaning the exterior of a furnace heat exchanger that includes a bundle of finned convection or bare radiant tubes heated when in use by the flue gases of a heater furnace. The apparatus comprises a motorized carriage 10 guided for movement along the outer surface of the bundle in a direction parallel to the tubes and a holder 24 on the carriage for holding a lance 20 in a position relative to the carriage 10 that permits the lance 20 to penetrate between the tubes of the bundle and to be advanced along the core by the carriage while remaining in the latter position.
