How is steam turbine design?

Steam turbines can come in all shapes and sizes, ranging from a single stage design to a multi-stage machine. A stage consists of a set of stator blades and a set of rotating blades and every stage and blade row is designed to provide the most efficient flow path and aerodynamic behavior possible.

What is the principle of steam generator?

A steam generator uses a bar-through, forced flow design to convert incoming water into steam during a single pass through a water coil. As water passes through the coil, heat is transferred from the hot gases, turning the water into steam.

How does a steam turbine generator produce electricity?

In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins/rotates the rotor shaft of a generator. The generator, in turn, converts the mechanical (kinetic) energy of the rotor to electrical energy.

What is the function of steam turbine?

A steam turbine is a device that extracts thermal energy from the steam and converts it to mechanical work on a rotating output shaft.

How does a steam turbine spin?

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 is working principle of steam turbine?

In simple terms, a steam turbine works by using a heat source (gas, coal, nuclear, solar) to heat water to extremely high temperatures until it is converted into steam. As that steam flows past a turbine’s spinning blades, the steam expands and cools.

What is the principle of turbine?

It works on the principle of Newton’s second law. It has a number of elliptical half-sized buckets fitted instead of blades on the rotor. When the water strikes the buckets at high speed, the rotor starts rotating, then the kinetic energy of water is converted into mechanical energy.
