ABSTRACT:
An improved apparatus for the speedy and efficient repair of tubes contained in a furnace boiler waterwall is disclosed. Disclosed are a milling machine used to mill the elongated slots, and drill and saw fixtures to aid in cutting away the damaged tube section. The improved apparatus enhances the precision and uniformity with which boiler tube repairs may be made, increases access to perform internal welds in boiler tubes and permits some prefabrication of necessary repair parts, thus reducing furnace down time for repair.
