INDIVIDUALLY REPLACEABLE AND REVERSIBLE INSERTABLE STEAM TURBINE NOZZLE

摘要

A reversible nozzle (10), removably attached to a fluid emitting base, such as a half turbine casing (22). The reversible nozzle (10) has a nozzle body (16) and a nozzle tube (12), with the nozzle body (16) preferably forming a plurality of fastener receiving slots (18, 18a). The nozzle tube (12) is angled with respect to the nozzle body (16). An installed reversible nozzle (10) is reversed by removing fasteners (34) connecting the nozzle body (16) to the fluid emitting base (22), rotating the nozzle body (16) about a normal nozzle body axis X, and resecuring the reversible nozzle (10) to the fluid emitting base (22) with fasteners (34). To aid in the alignment of the reversible nozzle (10), one fastener receiving slot (18a) is preferably elongated.
