In a nutshell, it is not correct to assign human attributes (e.g., lifetimes) to inanimate objects. Consequently, the operating span of a coal fired power plant can be unlimited since any degraded or failed component can be replaced with a new one. Some of the oldest U.S. coal plants have operated since 1921. The decision on whether to make a refurbishment, or to build a new plant, is merely a question of relative economics and investment risk. For example, the cost of a single replacement part is almost always less than the cost of replacing the plant. However, in an old plant, there is a risk that many additionally worn parts also will need replacement soon. Plant owners evaluate these tradeoffs each time a major component fails and make the decision whether or not to retire the plant.

Why do coal power plants have chimneys?

For steam from and, in emergencies, smoke to escape. CO 2 is colourless and so when the smoke is white, it is steam. When it is black or grey, it is soot, carbon that has not combined with oxygen correctly.

What is a coal-fired energy plant?

A coal-fired energy plant is one that burns coal (as the source of energy) to make electricity or drive machinery.

Where are the coal fired power plants in Canada?

Why is coal used in power plants?

It burns well and there has been abundant supplies of it. Coal was the whole basis of the industrial revolution that started in the 1700's, it was used to power staem engines. When electricity was discovered it was natural to apply this technology to generating electricity. Many countries had coal b ( Full Answer )

Use of urea at coal fired power plants?

Here is a novice explanation. Urea is used as a reactionary agent, reductant, in both Selective Catalyst Reduction (SCR) and Selective Non-Catalyst Reduction systems (SNCR) in order to reduce NO2 emissions and convert them into CO2 and water. Urea in an SCR is sprayed into the Flue Gasses before it ( Full Answer )

How many coal power plants?

There were 1493 coal fueled power plants in the United States in 2006. They produce about 50% of the country's electricity.

Why are solar power plants better than coal-fired power plants?

Solar gives of no pollution and does not require constant digging up of the earth to fuel them unlike Coal. But Solar only works during the daytime when the clouds are not blocking the sunlight. Solar also only produces a very small amount of power. Most panels provide less energy over their twenty ( Full Answer )

Which grade of coal is used in power plants?

Power plants are designed to use the available grade of coal. These may be anthracite, bituminous, lignite, high or low sulfur. What changes are the pollution control systems that are required to remove the generated air pollutants and the solid waste handling facilities.

How long is a coal power plant last?

Because coal is the most abundant fossil fuel in the world, a coal power plant can last for many, many years to come. It is also a cheaper fuel, which makes it more reliable than petroleum or natural gas.
