What are the parts of a steam turbine?

The main parts of a steam turbine are (1) the rotor that carries the blading to convert the thermal energy of the steam into the rotary motion of the shaft, (2) the casing, inside of which the rotor turns, that serves as a pressure vessel for containing the steam (it also accommodates fixed nozzle passages or stator …

Why does a steam turbine need vacuum?

Vacuum applies to steam turbines because the pressure of saturated vapour above available cooling water is well below 1 bar (typically 17 mbar at 15°C ambient). These shortcomings are examined and used to explain the anomalous response of a turbine to a copious supply of cold winter cooling water.

What are the parts of turbine?

The turbine components to be installed are the tower, nacelle, hub and blades.

What does steam do to a turbine?

As the name implies, a steam turbine is powered by steam. As hot, gaseous steam flows past the turbine’ spinning blades, steam expands and cools, giving off most of the energy it contains. This steam spins the blades continuously. The blades thus convert most of the steam’s potential energy into kinetic energy.

What are the two types of steam turbine?

Two types of steam turbines must be considered, condensing and noncondensing.

What is barometric leg?

A barometric leg is basically a condensate drain. In a vacuum system that is used to condense steam and condensable vapors through heat exchangers or condensers, the condensate is normally dropped into a receiver tank that is often vented to atmosphere or a low-pressure vent system.

How does a steam ejector work?

Steam ejectors use steam or gas instead of moving parts to compress a gas. In a jet or ejector, a relatively high-pressure gas, like steam or air, expands through a nozzle. The steam or air converts that pressure or potential energy to velocity or kinetic energy.

What are parts of steam?

STEAM fields are the areas of science, technology, engineering, the arts, and mathematics. STEAM is designed to integrate STEM subjects with arts subjects into various relevant education disciplines.

What is Curtis stage in steam turbine?

A Curtis stage impulse turbine is shown in Fig with schematic pressure and absolute steam-velocity changes through the stage. In the Curtis stage, the total enthalpy drop and hence pressure drop occur in the nozzles so that the pressure remains constant in all three rows of blades. Velocity is absorbed in two stages.

The main parts of a steam turbine are (1) the rotor that carries the blading to convert the thermal energy of the steam into the rotary motion of the shaft, (2) the casing, inside of which the rotor turns, that serves as a pressure vessel for containing the steam (it also accommodates fixed nozzle passages or stator vanes through which the steam is

What is a steam turbine generator?

Steam Turbine. In general, a steam turbine is a rotary heat engine that converts thermal energy contained in the steam to mechanical energy or to electrical energy. In its simplest form, a steam turbine consist of a boiler (steam generator), turbine, condenser, feed pump and a variety of auxiliary devices.
