Abstract
PURPOSE: To prevent occurrence of thermal distortion in the body of the line burner suited for use as a preheating means for welding, by forming the secondary mixing chambers and heat-shielding plates by applying a band-shaped pad divided into proper lengths on the outside of a tubular body of the burner.
CONSTITUTION: In the line burner used for heating longitudinal welding portion 14 of an article like the drum of a pressure vessel 1 to be welded, the secondary mixing chambers 15 are formed by applying the secondary mixing chamber defining pad 10 of steel plate in the form of a saddle-shaped band on the upper surface of a burner body 2 made of steel pipe. The pad 10 is divided axially of the body 2 into predetermined lengths L and coupled together. Here, heat-shielding plates 11 are formed by making slits in pad 10 symmetrically on both sides of the burner axis and bending the portions between these slits outwards. Further, the secondary mixture gas inlet ports 13 are formed on the outside of the body 2. Main nozzles 3 are formed in the burner body 2 at predetermined pitches, and the secondary nozzles 12 and auxiliary nozzles 4 are formed in the pad 10 in the manner that they are registered with respective main nozzles 3.
