Abstract: A machine for cleaning regeneration chambers of furnaces, the regeneration chambers having stacks of hollow refractory elements delimiting vertical passages, which define chimneys includes a self-propelled support structure to be introduced into a compartment, below the regeneration chamber to be cleaned, which communicates with the regeneration chamber. The machine further includes at least one lance, applied to the self-propelled support structure and configured to send within the vertical passages a stream of cleaning material powder and compressed air generated by a compressor positioned outside of the regeneration chamber to be cleaned, and at least one suction mouth, applied to said support structure and configured to suck cleaning material dust and aspirable materials from the ground, which were removed during the cleaning operation. At least one video camera is mounted on the support structure and at least one monitor controls from outside, through the video camera, operation of the machine.

Abstract: A method for cleaning tank melting furnaces for making glass items, provided with a melting chamber, which has a melting tank, to which a regeneration chamber is connected, of the type provided with at least one regenerator comprising a supporting structure for layers of refractory bricks, which are superimposed in a staggered arrangement so as to determine paths for the descent of the cooling exhaust gases that arrive from the melting chamber, the method consisting in sandblasting the exhaust gas descent paths and providing for the insertion of a delivery pipe for the delivery of an abrasive material through openings for access from the outside to the regeneration chamber and gradually into the exhaust gas descent paths.
