Science Quiz Electrical Generation Systems
Boiler / Combustion Chamber
Uses coal, natural gas, or petroleum to heat the water.
A series of pipes that transport water through the boiler as it changes to steam.
Water changed to steam with temperatures as high as 1000 degrees F.
Provides the source of mechanical energy for the generator.
A lower temperature steam that has lost energy after turning the turbine.
Produces the electricity.
Steps-up the voltage from 18,000 24,000 volts to as high as 675,000 volts.
A series of pipes that provide surface area to cool and condense the steam.
The water that is circulated through the condenser from a lake, river, or ocean.
Cooling Tower / Cooling Pond
Used to cool the water from the condenser.
Removes dust from the boiler exhaust fumes before being discharged into air.
A tall smokestack which allows the gases to go into the atmosphere.
This provides the mechanical potential energy for the process.
A tube bringing the water to the turbine.
Provides mechanical kinetic energy to the generator.
A pipe discharging water from the turbine to the downstream.
A rotating electrogmagnet inside the stator.
A small generator that energizes the rotor to create an electromagnet.
A stationary loop of wires around the rotor in which electricity is produced.
A large concrete building to contain accidental leaks.
A thick slab of concrete that surrounds the pressure vessel to absorb radiation.
Contains the superheated water that surrounds the core.
Core ( Fuel Rods)
Provides fission of U235 to produce heat.
Cadmium or boron rods that absorb neutrons to prevent an uncontrolled reaction.
Circulates around the core to transfer heat to the turbine steam-water system.
Transfers heat to the water circulating in the turbine system.
Water changed to steam to turn the turbine.
Provides mechanical energy to the generator.
Lower temperature steam that has left the turbine.
STeps up voltage to the power lines.
Changes the exhaust steam back to water.
Water from a river, lake, or ocean which passes through the condenser.
Cooling tower / Cooling Pond
The source for the coolant.
