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.

Many types of power plants generate electricity by boiling water to produce steam, which is then passed through a turbine. Plants that burn coal and biomass, nuclear plants, some natural gas plants, and even some solar facilities use this type of system.
How coal is used to generate electricity in a conventional coal-fired power plant with a pulverized coal boiler. Emissions Control. In the United States, gases produced by the combustion of coal in the boiler (called flue gas) must be treated to remove air pollutants before they can be released to the atmosphere through the power-plant stack.
Our pulverized coal boilers currently allow for ramp rate as fast as 6% per minute and down to 20% for hard coal and 35% for lignite based on BMCR. Contact GE Power for more information on the use of boilers in steam power plants.

An electric steam boiler is a type of boiler where the steam is generated using electricity, rather than through the combustion of a fuel source. Such boilers are used to generate steam for process purposes in many locations, for example laundries, food processing factories and hospitals.Although they are more expensive to run than gas-fired or
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.
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).

Coal trader’s web sites give base prices in the international market. We take a coal price of around 65 $ / Ton. The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 $ /hr; A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit.
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 .

First, we can know about the working principle of coal fired power generation boiler. The workings of a coal fired power station are simple and straight forward. The animation above simplifies the process. Initially coal is pulverized (D) and burnt in a furnace (C). The heat energy released is used to heat water into super hot steam which is then used to turn turbines (B). The turbines drive the generators (A) which produce electricity.
The greatest variation in the design of steam-electric power plants is due to the different fuel sources. Almost all coal, nuclear, geothermal, solar thermal electric power plants, waste incineration plants as well as many natural gas power plants are steam-electric. Natural gas is frequently combusted in gas turbines as well as boilers.
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.
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.
The Coal Gun is manufactured in Pennsylvania and burns anthracite coal. Although normally used in hydronic boiler applications, the Coal Gun can be adapted for use with forced hot air systems through the use of a water to air heat exchanger. With the optional steam control and fittings package, it can be used in steam heating applications as well.
