US4541247A - Steam turbine gland seal contro

A high pressure steam turbine having a sealing gland where the turbine rotor penetrates the casing of the turbine. Under certain conditions the gland is sealed by an auxiliary steam supply, and under other conditions the gland is self sealed by turbine inlet steam. A control system is provided to modify the temperature of the auxiliary steam to be more compatible with the self sealing steam

Dynamic Study of the Boiler Outlet to Turbine Inle

The steam hammer system extends from the outlet of the boiler superheater to the inlet of the steam turbine. The superheated steam exits the boiler at a temperature of 550 degC and a pressure of 260 bar abs and passes through the system at 2400 t/hr and a density of 85 kg/m3. In sections of the system the steam velocity is as high as 50m/s.
