Steam turbine - Wikipedia
A steam turbine or steam turbine engine is a machine or heat engine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft.
This paper discusses the basic steam turbine design philosophy used by GE and summarizes some of the key technology programs which will support steam turbine designs for the ’90s. OVERALL DESIGN APPROACH The design of reliable, efficient steam turbines requires the application of many diverse areas of
Two separate components are provided: the steam turbine to con vert the thermal energy to rotating mechanical energy, and the generator to convert the mechanical energy to electrical energy. Typically, the turbine is directly coupled to the gen erator. This chapter provides a general overview of steam turbine generators.
The project included design to facilitate the operation and maintenance of the steam turbine generator. The research looks into the complete cycle of structure of steam tur-bine generators. The cycle of designing the structure included the loading, aesthetic, functionality of the structure.
electrical generator. A characteristic of the steam turbine is the ability to produce high power outputs in a fairly compact machine though steam turbines are by no means small. Although simple in concept, turbine design has evolved to improve the internal efficiency. Steam turbulence and fluid friction have been minimized by refinements to

The steam is admitted main through stop valves and subsequently through a set of control valves. Each of these control valves admits steam through. a different set of nozzle sections. Since these sec-tions have been distributed around the periphery of the first stage, they divide the steam admission into partial arcs.
Steam turbines consist essentially of a casing to which stationary blades are fixed on the inside and a rotor carrying moving blades on the periphery. The rotor is fitted inside the casing with the rows of moving blades penetrating between the rows of fixed blades.
Turbine-generator foundation is a complex engineering structural component. Different types of turbine foundation are used for different machines depending on their capacity, geometrical sizes and constructional features.
