i am very much confused about direction of thrust in steam
turbine...we have steam turbine of 13 stages,10 stages of
impulse and 3 of reaction type....in study manual direction
of thrust is towards inlet but on thrust bearing its loading
side is towards condenser(exhaust side) wile also dummy ring
is present in design which also restrict rotor to move in
exhaust side direction not inlet ....

Answer Posted / noor mohamed
HI freind u mentioned that 3 stages were reaction type generally reaction type expansion is done for high pressure side of turbine (major axial thrust acting on this side) and impulse type expansion is done at Low pressure side and also thrust direction depends on the side at which the steam is entering and leaving.if u have any images of ur problem statement that ll give a clear picture Thanks
