Metallurgical coal is most widely used by the steel industry, with 70 percent of the world''s steel output dependent on coal. In addition, coal finds its way into many different products, such as the carbon fiber that strengthens everything from auto bodies to building materials.
Coal is also used to produce very high temperatures through combustion. Efforts around the world to reduce the use of coal have led some regions to switch to natural gas and electricity from lower carbon sources. When coal is used for electricity generation, it is usually pulverized and then burned in a furnace with a boiler.

The present chapter reviews those factors likely to influence coal use, especially domestic coal use, over the periods of interest to this study, namely, nearterm (), midterm (), and longterm () planning horizons. The introductory section on markets for coal and ...
Coal is primarily used as fuel to generate electric power in the United States. The coal is burned and the heat given off is used to convert water into steam, which drives a turbine. In 2012, about 39 percent of all electricity in the United States was generated by coalfired power plants, according to the Energy Information Administration.

Agricultural Uses of Coal and Its Products
Thousands of different products have coal or coal byproducts as components: soap, aspirins, solvents, dyes, plastics and fibres, such as rayon and nylon. Coal is also an essential ingredient in the production of specialist products: Activated carbon used in filters for water and air purification and in kidney dialysis machines.
New Uses for Coal Byproducts. The dry coal ash produced by fossil fuel plants isn''t just waste—the gypsum, fly ash and slag it contains can be sold for reuse in commercial building materials and more. In 2009, TVA made a to 2 billion commitment to transfer all coal .
Coal tar: It is obtained as a byproduct in the process of making coke. Though its colour is the same as coke, tar is a highly viscous liquid. It also has an extremely unpleasant smell. Uses: Coal tar is widely used to manufacture paints, perfumes, synthetic dyes, photographic material, drugs and explosives.
Feb 06, 2019· Coal and its byproducts have found numerous uses over the years. The following are some of the most noteworthy uses of this fossil fuel. Electricity Generation. Coal is mainly used in coalfired power plants to generate electricity. It is a reliable and lowcost energy source. In the US, about 50% of electricity is generated from coal.
What Are the Uses of Cobalt? ... Most cobalt used in the United States is imported. Alloys in Industry. Alloys, or mixtures of metals, make up half the cobalt used each year. Some alloys go into making jet engines and gas turbine engines. Another alloy, called Alnico, consists of of aluminum, nickel and cobalt and is strongly magnetic.
Coal is classified into four main types, or ranks, based on carbon and heat content. The general rule is that the higher the grade of coal, the cleaner it burns and the more versatile its uses.
Coal is used for various purposes, its major uses are: (i) Coal as a source of steam energy: Coal is the major source of steam energy since Industrial Revolution. At that time, most of the machines were run on coalbased energy. Railway locomotives and ship engines used coal as the only source of energy.
Apr 25, 2018· Examples of fuels include gasoline, coal and alcohol. Most of the fuels come from nonrenewable sources; once used, they are gone forever. Each day, people bathe, cook, clean, do laundry and drive using various types of fuels. A quick review of different fuels reveals the important roles they play in daily life.
Coal evaluates DOE''s performance and recommends priorities in updating its coal program and responding to EPACT. This volume provides a picture of likely future coal use and associated technology requirements through the year 2040.
Coal is India''s primary source of energy (equaling 44% of total energy consumption), and the country ranked as the thirdlargest global coal producer, consumer, and importer of coal in 2012. Despite its significant coal reserves, India has experienced increasing supply shortages as a result of a lack of competition among producers, insufficient ...
Coal is also used in manufacturing. If coal is heated the gases, tars, and residues produced can be used in a number of manufacturing processes. Plastics, roofing, linoleum, synthetic rubber, insecticides, paint products, medicines, solvents, and synthetic fibers all include some coalderived compounds.
Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite. Bituminous usually has a high heating (Btu) value and is the most common type of coal used in electricity generation in the United States. Bituminous coal appears shiny and smooth when you first see it, but look closer and you may see it has layers.
Through the process of coal gasification to produce synthetic natural gas there are several useful byproducts that can be made: Dephenolized Cresylic Acid. Dephenolized cresylic acid is used in the production of industrial solvents, industrial resins and antioxidants. It is also used in .
ADVERTISEMENTS: Six main uses of petroleum are as follows: (i) Transportation (ii) Industrial power (iii) Heating and lighting (iv) Lubricants (v) Petrochemical industry (vi) Use of byproducts. Petroleum, nowadays, is a main source of energy in the world. This is also due to its multiple usability in different fields of machine civilisation.
Many Asian countries do not have enough natural energy resources to cover energy needs and must import coal to meet those requirements. Approximately billion tons of hard coal and 1 billion tons of brown coal were used globally in 2013. Seventy percent of the steel produced in 2014 used coal in its production. Global crude steel production ...
Coalfired power stations generate 40% of global electricity. Heat from burning coal boils water, and steam spins a propeller. A machine turns this into electricity. About 70% of steel is created using coke, a highcarbon fuel made from coal. It is burned to melt and remove impurities from iron ore ...
There are four main coal types: lignite, subbituminous, bituminous and anthracite. Here''s a look at their characteristics and uses. Found in the earth''s crust, coal is a fossil fuel that is ...
