What is Coal explain its different types and uses?

Answer. Coal types: Hard coals. Bituminous coal is harder and blacker than lignite and sub-bituminous coal, and can be divided into two types: thermal and metallurgical. The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel.

Which grade of coal is mostly mined in India?

Bituminous: It is a medium grade of coal having high heating capacity. It is the most commonly used type of coal for electricity generation in India. Most of bituminous coal is found in Jharkhand, Odisha, West Bengal, Chhattisgarh, and Madhya Pradesh.

What is the difference between the types of coal?

Anthracite: The highest rank of coal. … 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.

Which Southern state is the largest producer of coal?

West Virginia is the largest coal-producing state in the region and the second-largest coal-producing state in the United States. Underground mines supplied 78% of the coal produced in the Appalachian region. Underground mines in the Appalachian region produced 56% of U.S. total underground coal mine production.

What are the disadvantages of coal?

The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.

What is the chemical formula of coal?

Coal is divided into four classes: anthracite, bituminous, sub-bituminous, and lignite. Elemental analysis gives empirical formulas such as C137H97O9NS for bituminous coal and C240H90O4NS for high-grade anthracite. Anthracite coal is a dense, hard rock with a jet-black color and a metallic luster.

Why is coal still used today?

In a world where carbon emissions are not taxed, coal is a very inexpensive and efficient way to generate electricity. Coal is also one of the most abundant energy sources in the entire world, and it’s relatively efficient for generating electricity. … Most of the coal we export is used for steel production.

Why is coal bad for the environment?

The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. … Coal-fired power plants release more greenhouse gases per unit of energy produced than any other electricity source (1).

Does coal absorb water?

Coal is known to absorb water when soaked in it. … Therefore it is very important, in judging whether a coal will make a good CWM, to know the factors which influence its moisture- holding capacity.

What is the major use of coal?

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.

What is PCI coal used for?

Pulverised Coal Injection coal (PCI) – coal used for its heat value and injected directly into blast furnaces (without an intermediate coking phase) as a supplementary fuel, which reduces the amount of coke required and therefore costs. PCI coal can also be sold into the thermal coal market.
