How does a steam power plant works?
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.
How does a steam turbine rotate?
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.
Why is it that steam turbine lube oil needs centrifuging?
The high solvency of modern oil would remove nearly all the deposits left behind by the old oil, thus reducing the life of the clean oil. Before refilling, therefore, it is advisable to continuously centrifuge with a warm water wash at approximately 180°F.
How does a waste oil centrifuge work?
A bowl centrifuge spins the oil, with particulate settling out against an inside wall of the bowl. A layer of water forms on top of the hard particles, followed by a layer of water/oil emulsion and then a layer of oil that progressively becomes cleaner toward the center of the bowl.
What are the four basic components of a steam power plant?
Steam Power Station: Components, Application, and Working…
- Steam Boiler.
- Steam Turbine.
- Condenser.
- Generator.
- Alternator.
Which turbine is used in steam power plant?
In order to match steam production to heat demand, there are three types of steam turbine in common use for CHP plants. These three are called a back pressure steam turbine, an extraction steam turbine and a condensing steam turbine. Each type will suit a different configuration of plant.
Why is a steam turbine compounded?
Compounding of steam turbine is used to reduce the rotor speed. It is the process by which rotor speed come to its desired value. A multiple system of rotors are connected in series keyed to a common shaft and the steam pressure or velocity is absorbed in stages as it flows over the blades.
How does turbine works in power plant?
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.
Can steam turbine operates without lubrication?
Steam turbines cannot operate without lubrication. Therefore, turbine lubricating oil systems must be designed, operated and maintained for extreme reliability. Lubricating oil systems affect overall facility loss prevention more than most mechanical systems.
Why lube oil is used in turbine?
Aero-derivative gas turbines require that the oil not only lubricates under more severe thermal and oxidative conditions, but that oil serves as a heat transfer fluid as well, carrying heat away from the bearings and shafts.
Does centrifuge separate oil and water?
Instead, the centrifuge applies a process whereby the crude oil is passed through two parallel three stage separation trains to separate oil, gas and water. The oil then passes through the banks of the centrifuges to separate out the emulsion to produce in-spec export oil.
Why is it important to balance the centrifuge?
Why you need to balance a centrifuge Prior to starting the centrifuge, it is necessary to load it correctly. Balancing the centrifuge prevents potential damage to the instrument, and is crucial for safe operation.
