Question: What is the principle of operation of steam power plant?

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 operation of steam power plant *?

What is the principle of operation of steam power plant? Explanation: The Rankine cycle is an idealized thermodynamic cycle of heat engine. Under this cycle heat energy is converted into mechanical energy while undergoing phase change.

What is the principle of power plant?

Background principles. Electrical power generation is based on Faraday’s law of mutual electromagnetic induction: in an electrical circuit moving (e.g. rotating) so that it cuts magnetic lines of force, an e.m.f. is generated that is proportional to the rate at which unit lines of force are cut.

What is the principle of operation of steam turbine explain with neat sketches?

Basically,in a steam turbine pressure energy of steam extracts and then it converted into kinetic energy by allowing the steam to flow through thew nozzles. The conversion of kinetic energy does mechanical work to the rotor blades and the rotor is connected to a steam turbine generator which acts as a mediator.

What is the basic principle of regeneration?

What is the basic principle of regeneration? Explanation: In regeneration steam from condenser is circulated through turbine to increase steam temperature before it enters boiler. Explanation: Feedwater is preheated so as to decrease the fuel consumption which increases efficiency.

What is a function of steam in a plant?

The stem’s main role is to hold onto the plant buds, flowers, leaves, and fruits. A stem helps the plants together with the roots, helping them stand up straight and perpendicular to the ground.

What is steam power plant?

A steam power plant consists of a boiler, steam turbine and generator, and other auxiliaries. The boiler generates steam at high pressure and high temperature. The steam turbine converts the heat energy of steam into mechanical energy. The generator then converts the mechanical energy into electric power.

What are the components of a steam power plant?

What are the components of a Steam Power Plant? Explanation: A Steam Power Plant has the sequence, Boiler, Turbine, Condenser, Pump.

Is steam power plant and thermal power plant same?

A steam/thermal power station uses heat energy generated from burning coal to produce electrical energy. This type of power station is widely used around the world.

Power Generation/Steam Power.

What is principle of steam turbine and what are the different types of steam turbines?

Two basic types of steam turbine designs are available. One is an impulse design in which the rotor turns as a result of the force of steam on the blades. The other is a reaction design, and it operates on the principle that the rotor derives its rotational force from the steam as it leaves the blades.

What is a turbine principle?

Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Click NEXT to learn more.

What is the operating principle of an impulse turbine?

Impulse turbine works on the basic principle of impulse. When the jet of water strikes at the turbine blade with full of its speed, it generates a large force which used to rotate the turbine. The force is depends on the time interval and velocity of jet strikes the blades.

What is main function of moderator?

Moderators are the substance that slows down the neutrons in nuclear reactors. Moderators are made up of materials with light nuclei that do not absorb the neutrons but slow down the speed of neutrons by a series of successive collisions.

What is regeneration in power plant engineering Mcq?

Explanation: In the process of regeneration, energy is exchanged internally between the expanding fluid in the turbine & the compressed fluid before heat addition. … Explanation: Here heaters are assumed to be adequately insulated, & there is no heat gain from or heat loss to, the surrounding.

How can be the plant efficiency of steam power plant is increased Mcq?

using high temperature and high pressure steam. … The efficiency of the plant mainly depends upon pressure and temperature of the steam entering the turbine and pressure in the condensor. The thermal efficiency increase with the increase in temperature and pressure of the steam entering the turbine.
