The coal produced from ancient plant material makes it the best for producing electricity. The electricity generated does have its impact on the environment. Therefore, it is not the most recommended way of generating energy like in case of alternative energy sources.
A coal or oil steam power plant produces electricity. Coal is the most available fuel, has a rather stable price and as a result is the most cost-effective fossil-fired technology. Nowadays, crude oil or heavy fuel oil have become quite unusual as fuels for electricity generation purposes.
For decades, coal represented roughly half of the nation’s electricity generation, but in recent years this percentage of coal-fired generation has begun to decline.
This formation of steam is seen in coal-fired power plants, nuclear reactors, or even by sunlight in a solar thermal power plant. This steam is an important part in electrical generation since it can be used to spin a turbine (which is connected to a generator to create power).
approximately 80% of U.S. coal production is burned in electric plants. However, the main reason we are considering switching away from coal is burning coal is one of the most challenging environmental problems. For purposes of the course, we consider steam generation from coal as steam generation from biomass; both fuels are fairly similar.

Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel.
Boiler (power generation) Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator .
