AI Technical Summary

Benefits of technology

This technology allows for easier maintenance without having complex pipe arrangements or extra stations needed by traditional methods like shutdowns. It also simplifies the process when two different types of fluid flow through separate parts of the system.

Problems solved by technology

Technics: Steamed Turbo generators use excessive amounts of water during startup due to increased demand on them's ability to generate electricity without adding extra equipment or requiring additional pipe lines. Overall, these technical problem addressed through the design of new systems can improve efficiency while reducing costs associated with starting up such machines.

Embodiment Construction

[0018]FIG. 1 shows an assembly 1 according to the prior art. The assembly 1 comprises a steam turbine 2 with a two-shell casing (not shown) which comprises an outer casing 3 and an inner casing (not shown) arranged therein. Furthermore, the steam turbine 2 comprises a connection 4 guided through the outer casing 3. The steam turbine 2 comprises a rotatably mounted rotor and an inflow region 5 for a fresh steam. The inflow region 5 is fluidically connected to a fresh-steam line 9. In this fresh-steam line 9 there are arranged a quick-closing valve 7 and a control valve 8. Furthermore, the arrangement 1 comprises a branching 9. At this branching 9 there is arranged an overload line 10 which opens into an overload inflow region 11 in the steam turbine 2. In the overload line 10 there is arranged an overload valve 12 which is arranged in the actual structure below the steam turbine 2, which leads to disadvantages.

[0019]In normal operation, a fresh steam flows via the fresh-steam line 6 and
