Heat from the geothermal fluid causes the secondary fluid to flash to vapor, which then drives the turbines and subsequently, the generators
. Binary cycle power plants are closed-loop systems, and virtually nothing (except water vapor) is emitted to the atmosphere.
What is the advantage of a binary cycle power plant?
A binary power plant has several advantages such as
reservoir sustainability
, high reliability operation, and environmental friendliness.
Which plant runs on binary cycle?
A binary cycle
geothermal power plants
first has two circuits; the first uses pumps to draw hot water from a geothermal well through a heat exchanger before returning it to the underground reservoir at a lower temperature.
What are binary cycles give examples?
Binary cycle powerplant is
a type of geothermal power plant that allows cooler geothermal reservoirs to be used than is necessary for dry stream and flash steam plants
.
What are binary power plants?
A binary cycle power plant is
used where geothermal resources are not sufficiently hot to produce steam, or where the source contains minerals or chemical impurities to allow flashing
. In the binary cycle process, the geothermal liquid is passed through a heat exchanger.
How does power plant generate electricity?
Coal-fired plants produce electricity
by burning coal in a boiler to produce steam
. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
How does geothermal work?
Geothermal power plants
use steam to produce electricity
. The steam comes from reservoirs of hot water found a few miles or more below the earth’s surface. The steam rotates a turbine that activates a generator, which produces electricity.
What is a binary cycle power plant Mcq?
Explanation: A binary cycle power plant is
a type of geothermal power plant that allows cooler geothermal reservoirs to be used than is necessary for dry steam and flash steam plants
.
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.
Do power plants generate AC or DC?
The power station generates AC and not DC
because the transmission of alternating current is easier and very efficient. The transformers can step up and step down the voltage of the alternating current.
What power plant produces the most electricity?
| Rank Station Country | 1. Three Gorges Dam China | 2. Itaipu Dam Brazil Paraguay | 3. Xiluodu China | 4. Belo Monte Brazil |

What volcano is nearest to the power plant?
Located on the Lower East Rift Zone of the
Kilauea volcano
, the Puna Geothermal Venture (PGV) plant generates around 30% of the island’s electrical power by bringing steam from the underground wells into a turbine generator.
How energy is harnessed from hydrothermal?
How is hydrothermal energy harnessed? Geothermal energy is produced by the heat of Earth’s molten interior. This energy is harnessed
to generate electricity when water is injected deep underground and returns as steam (or hot water, which is later converted to steam) to drive a turbine on an electric power generator
.
Which gas is released in hydrothermal resources?
Hydrothermal vents are usually associated with emission of gases such as
helium, methane, and hydrogen sulfide
; and deposition of large quantities of metallic compounds on the seafloor. In fact, hydrothermal activity is often identified by detection of anomalies of such emissions and depositions.
How does steam power plants work?
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
.
Which power plant requires more space?
| Power Station Rank Space required | Hydro Power station 4 Needs very large space for constructing a dam | Diesel Power station 1 Needs very little space for all equipment | Nuclear Power station 3 Needs the least space, compared any other power station of equal capacity |

What happens on bleeding to reheat feed water to boiler?
Explanation: Bleeding
decreases the thermal efficiency of the cycle
as it reheats feed water to the boiler. Explanation: A regeneration is done to increase the efficiency of a reheat cycle so naturally the efficiency of a regenerative cycle is much more than a Rankine cycle.
