| Gas Turbine V94.2 |
| V94.2 is a heavy-duty Gas Turbine designed for reliable
,efficient ,and flexible operation. Until January 2002 more than 200 Siemens turbines of this
type were in operation,
have been shipped or ordered worldwide. |
| |
| Main Features: |
-16
Stages-Adjustable first stator row.
-NACA profiles - pressure ratio 11.
-Equiaxed NI-base super alloys castings.
-NICoCrAIY VPS coatings (1st + 2nd stages)-Chromising
(3rd blade).
-4 stage design; optimum as far as aerodynamic
efficiency and losses due to cooling air consumption.
|
 |
|
-First and second stages forced convection cooled.
-2vertical silo-type large volume combustors.
-Double walled flame tube with ceramic tiles.
-Single Wall inconel mixing chamber and hot gas casing.
-2 x 8 burners (same size-different number for different
GT size. |
