A welded rotor, a steam turbine having a welded rotor, and a method of producing a welded rotor are disclosed. The welded rotor includes a high pressure section and an intermediate pressure section. The high pressure section includes a high temperature material section joined to a low temperature material section.

Welded rotor, a steam turbine having a welded rotor and a method for producing a welded rotor

A steam turbine with a drum rotor utilizing individual nozzle ring assemblies in the IP section incased by a single shell. In one embodiment, a steam turbine has a high pressure (HP) section with a double shell drum and an intermediate pressure (IP) section with a single shell drum, with the IP section including a plurality of individual nozzle ring assemblies axially spaced along the single shell casing, such that each nozzle ring assembly surrounds the drum rotor. In other embodiments, a low pressure section (LP) of the steam turbine can have a single-flow or dual-flow connection to a condenser, and the condenser can be positioned to the side, vertically below, or axially aligned with the LP section.

A method and a system for determining radial clearances in a rotating machine are provided. The rotating machine includes at least one shell, at least one rotor, and at least one stationary component. The method includes creating a finite element model for at least one component within the rotating machine, creating a cycle deck data file for the rotating machine, determining an initial clearance versus time, and determining an initial clearance versus location. The system includes a client system including a browser, a centralized database for storing machine information, and a server system configured to be coupled to the client system and the database wherein the server system is further configured to receive machine information from the client system, store finite element model information in the centralized database, track machine information, update the centralized database periodically with newly received machine information to maintain machine information, and provide machine information in response to an inquiry.

Cooling of a workpiece is conducted at selected workpiece locations in accordance with predetermined heat flux, at the locations, required to result in a desired workpiece cooling rate for workpiece integrity, microstructure and mechanical properties. A cooling fluid is controlled to follow the workpiece surface according to preselected cooling fluid convective cooling parameters including, but not limited to, cooling fluid direction, mass flow rate, and velocity at the selected locations.
