Abstract

PURPOSE: To get a high temperature nozzle without thermal fatigue fracture due to fiuid leak, by inserting aslant a thermal sleeve in the nozzle for eliminating any clearance between the sleeve and nozzle.
CONSTITUTION: The nozzle 2 is slanted downward with a certain axial angle α and a thermal sleeve 1 having an inverted conical head 1a and a fluid passage inside is inserted in the nozzle 2. The surface of contact between the sleeve head 1a and the nozzle socket 3 is tapered, so that even if a clearance is produced there, the weight of the sleeve itself and the dynamic pressure of the inflowing fluid make the sleeve side down the tapered surface to eliminate or block the clearance.
