Title:
STEAM-TURBINE ASSEMBLY AND A METHOD FOR OPERATING A STEAM-TURBINE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO2002027152
Kind Code:
A3
Abstract:
The invention relates to a steam-turbine assembly (2) comprising a vacuum pump device (14), containing a jet pump (26) and a liquid-ring pump (28) positioned in series one behind the other. The steam (D) that accumulates in the assembly (2) is used as the driving medium (T) for the jet pump (26), preferably mixed with air (L). This allows the liquid-ring pump (28), located downstream, to have comparatively small dimensions. The vacuum pump device (14) is preferably configured as a central vacuum pump system for the steam-turbine assembly (2) and purges a number of components in the assembly (8,18,22).
