Question

True or False... In coal-fired power plants, coal is burned to produce steam, which is then used to turn a turbine.
So i think false but i want to make sure..

Answer 1

Its true.

Answer 2

Burning coal in itself does not create electricity. Burning coal and using the heat to power turbines or generators is the manner in which electricity is created. -----------oooooooooooooo-------------Coal is used to boil water to steam. Steam is used to turn a turbine (a type of steam engine). The turbine turns an electric generator (dynamo or alternator) and electricity is generated. Those big fat towers outside power stations, that newsreaders try to convince us are chimneys, are actually water recycling, cooling towers.

Answer 3

so its true? i seem to over think the simplest question.. i understand that coal cant be burned to make steam but it can be burned to boil water that makes steam.. so im confused.

Answer 4

Yes its true. haha Like in old train engines where coal is heated and then used to produce steam to power the train.

Answer 5

1. Heat is created
Before the coal is burned, it is pulverized to the fineness of talcum powder. It is then mixed with hot air and blown into the firebox of the boiler. Burning in suspension, the coal/air mixture provides the most complete combustion and maximum heat possible.

2. Water turns to steam
Highly purified water, pumped through pipes inside the boiler, is turned into steam by the heat. The steam reaches temperatures of up to 1,000 degrees Fahrenheit and pressures up to 3,500 pounds per square inch, and is piped to the turbine.

3. Steam turns the turbine
The enormous pressure of the steam pushing against a series of giant turbine blades turns the turbine shaft. The turbine shaft is connected to the shaft of the generator, where magnets spin within wire coils to produce electricity.

4. Steam turns back into water
After doing its work in the turbine, the steam is drawn into a condenser, a large chamber in the basement of the power plant. In this important step, millions of gallons of cool water from a nearby source (such as a river or lake) are pumped through a network of tubes running through the condenser. The cool water in the tubes converts the steam back into water that can be used over and over again in the plant.

The cooling water is returned to its source without any contamination, and the steam water is returned to the boiler to repeat the cycle.

Answer 6

ok..ok lol i seriously over thought this lol Thanks! Ya'll helped alot!!
