3.5 tonns of coal is required for producing 1 mw
Not really. You receive 100 times as much radiation from coal power plant pollution than you do from nuclear power plant leaks.
The power varies, but sizes in the range of 2000 to 3000 megawatt are common.
The amount of energy generated from coal can vary based on factors such as the type and quality of coal, the efficiency of the power plant, and the technology used. On average, coal-fired power plants convert about 33-40% of the energy in coal into electricity.
how much electrical power can be provided by coal
A conventional plant costs about $780 million to build, according to Bechtel...a comparable coal-gas plant would cost about $975 million. source: http://money.cnn.com/2004/10/18/news/economy/coal/
The amount of coal used each day can vary widely based on factors such as the size of the power plant, its efficiency, and the electricity demand. On average, a coal-fired power plant might consume thousands of tons of coal per day to generate electricity.
Coal power plants typically produce around 2-3 kilowatt-hours (kWh) of electricity for every pound of coal burned. The energy produced can vary depending on the efficiency of the plant.
The amount of fuel needed to run a power plant for one day will vary depending on the type of fuel used (e.g., coal, natural gas, nuclear). For example, a coal-fired power plant may require several thousand tons of coal per day, while a natural gas power plant may need thousands of cubic meters of natural gas. The specific fuel consumption rate of the power plant and its efficiency will also impact the amount of fuel needed.
Coal releases about 14-15,000 btu's of heat per pound. This will on average produce about 12 lbs of high quality superheated steam. With a **steam rate of an engine at about 4 lbs of steam per kilowatt produced, this coal plant can produce about 3 kilowatts per pound of coal burned. So to produce 10 MW of electricity this hypothetical plant will burn about 3,334 lbs. of coal per hour. In a day the coal consumed will be about 80, 000 lbs or 40 tons. *Actual fuel conditions, combustion efficiency, boiler efficiency and engine efficiency would need to be determined for any particular power plant to determine actual coal usage in that plant. **steam rates of different power plants can range from about 3.5 lbs steam/ KW to more than 10 lbs of steam/ KW.
Single nuclear PWR units can now range up to 1600 MWe output, so I think that is comparable with any single coal fired unit
Much cleaner than coal powered plants (no emissions) - although there is nuclear waste Produce relatively cheap energyProduces extremely large amount of energy compared to a coal plant
