Difference Between Coking Coal and Thermal Coal

Thermal coal, also called steaming coal, has a lower energy content and higher moisture and is used to generate electricity. Metallurgical or coking coal has a higher energy content and lower moisture and is used to make iron, steel and other metals.

Is coking coal thermal coal?

Metallurgical coal produces strong, low-density coke when it is heated in a low-oxygen environment. On heating, the coal softens, and volatile components evaporate and escape through pores in the mass. ... Metallurgical coal contrasts with thermal coal, which does not produce coke when heated.

What is the difference between coking coal and non coking coal?

Non Coking Coal does not have any caking properties and it is mainly used as thermal coal for power generation. It has a higher ash content and also used in industries like cement, fertilizer, glass, ceramic, paper, chemical and brick manufacturing.

What is coking coal used for?

Coking coal, also known as metallurgical coal, is used to create coke, one of the key irreplaceable inputs for the production of steel. There are many varieties of coal in the world, ranging from brown coal or lignite to anthracite.

What is thermal coal?

Thermal coal, also known as 'steaming coal' or just 'coal', is widely used as the principle means of generating electricity in much of the world. ... (Thermal coal differs from coking coal, which has a higher energy content and is chiefly used in metal making rather than electricity production.)

What is Coke vs coal?

What is the difference between coal and coke fuel? Coal is a shiny, black fossil fuel that contains impurities, emits smoke when burned, and produces less heat than coke. Coke is a dull, black byproduct of coal that burns hotter and cleaner.

Can steel be made without coking coal?

Now, nearly all new steel globally is produced using iron oxide and coking coal. ... While an increasing amount of steel is being recycled, there is currently no technology to make steel at scale without using coal.

What are the 4 grades of coal?

Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.

What is the best grade of coal?

Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter. Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite.

How is Coke coal?

Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.

Is there an alternative to coking coal?

Blast furnaces need coal, but there is an alternative technology called an Electric Arc Furnace (EAF). This is responsible for approximately 30% of the world's steel production and does not require coal.

What is the current price of coking coal?

Australia Coal Price is at a current level of 86.74, down from 86.83 last month and up from 67.64 one year ago.
