, into the condenser 14 via the high-pressure turbine bypass valve 32 , and the internal steam residual energy of the low-pressure turbine inlet pipe 12 is transferred from the low-pressure turbine inlet pipe 12 to the low-pressure turbine bypass pipe 35 . When introduced into the condenser 14 via the low-pressure turbine bypass valve 33, the internal steam residual energy in the vicinity of the turbine is reduced, eliminating the need for check valves in the oil air pipes 23,24. By omitting the check valve, manufacturing costs are reduced, of course, and design constraints are reduced, making design easier.
