DUAL-FLOW STEAM TURBINE WITH STEAM COOLING

A dual flow steam turbine includes coolant passageways which extract coolant steam from the main steam flow paths at locations downstream from the inlet. The coolant passageways conduct the coolant steam through portions of the dual flow steam turbine which are subjected to a high temperature flow....

Beschreibung
Zusammenfassung:	A dual flow steam turbine includes coolant passageways which extract coolant steam from the main steam flow paths at locations downstream from the inlet. The coolant passageways conduct the coolant steam through portions of the dual flow steam turbine which are subjected to a high temperature flow. In some cases, the passageways conduct the coolant steam through first stage nozzle boxes and an inlet assembly of the dual flow steam turbine. In some cases, the inlet assembly of the steam turbine includes an annular diaphragm, and a coolant passageway passes through the annular diaphragm to help cool the annular diaphragm.
