Abstract

Peak load device of a multistage turbine, having a high pressure turbine section with an inlet pipe supplying working medium and an exhaust steam outlet, a subsequent turbine section having an inlet pipe connected to the exhaust steam outlet of the high pressure turbine section for receiving the exhaust steam thereof, a bypass line connected from the high pressure turbine section inlet pipe to the subsequent turbine section inlet pipe through which part of the working medium bypasses the high pressure turbine section as a bypass flow, including a jet compressor inlet disposed at the connection of the bypass line to the subsequent turbine section inlet pipe for receiving the bypass flow as a motive medium while increasing the pressure of the flow through the subsequent turbine section inlet pipe.
