Abstract

PURPOSE: To prevent the damage of a structure inside a furnace by providing projections on the periphery of the lower part of a mixer and fitting the projections into the slots formed on the inner periphery of the upper part of a diffuser and connecting the mixer and the diffuser in such a manner that they may not be pulled out and then by preventing the dispersion of integrated weld.
CONSTITUTION: Two projections 28 are formed on the outer periphery of the lower part of a mixer 15. The two projections 28 are so placed as to face each other oppositely apart from the central axis of the mixer of cylindrical shape. On the inner periphery of the upper part of a diffuser 16 are formed slots 29 into which the projections 28 can be fitted. On the upper part of the slots 29 are provided notches which allow the projections to be inserted. The lower part of the mixer 15 is set to the upper part of the diffuser so that the projections 28 may be placed in the notches 30. And then, the mixer 15 is lowered and turned, allowing the projections 28 to be fitted into the slots 29. Both the projections and slots are engaged in an integrated block. This construction serves to maintain the state of connection between the mixer 15 and the diffuser 16, even if elbows 13 are separated from a transition piece 12. Therefore, the structures inside the furnace can not be dispersed and the damage can be prevented.
