coal 4b

Coal (from the Old English term col, which has meant "mineral of fossilized carbon" since the 13th century) is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.

Coal has many significant uses worldwide. According to the World Coal Association; “Coal is a combustible, sedimentary, organic rock, which is composed mainly of carbon, hydrogen and oxygen. It’s formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams. Coal is a fossil fuel and is far more plentiful than oil or gas, with around 112 years of coal remaining worldwide.”

The most significant uses are in electricity generation, steel production, cement production and as a liquid fuel. Around 6.6 billion tons of hard coal was used worldwide last year. Since the year 2000, global coal consumption has grown faster than any other fuel. The five largest coal users – China, USA, India, Russia and Japan – account for 76% of total global coal use.

Different types of coal have different uses. The main ones are:

A. Coking Coal – also known as Metallurgical Coal – is mainly used in steel production.
B. Steam Coal – also known as Thermal Coal – is mainly used in power generation.

We are directly connected to three coal miners who sell quality Coal – both A and B.
The origin of this product is Colombia, Chile and South Africa. We can supply volumes up to 500,000 MT by month from both sources at competitive prices. Your enquiry must include your target levels – Calorific value range – max, Sulphur content – Volatile Matter – Moisture – Target price.

HELPFUL INFORMATION

The biggest market for coal is Asia, which currently accounts for over 67% of global coal consumption; although China is responsible for a significant proportion of this. Many countries do not have natural energy resources sufficient to cover their energy needs, and therefore need to import energy to help meet their requirements. Japan, Chinese Taipei and Korea, for example, import significant quantities of steam coal for electricity generation and coking coal for steel production.

LIGNITE, or Brown Coal, is the lowest rank of coal and used almost exclusively as fuel for electric power generation.

SUB-BITUMINOUS COAL, whose properties range from those of lignite to those of bituminous coal, is used primarily as fuel for steam-electric power generation.

BITUMINOUS COAL, is a dense sedimentary rock, usually black, but sometimes dark brown, often with well-defined bands of bright and dull material; it is used primarily as fuel in steam-electric power generation, with substantial quantities used for heat and power applications in manufacturing and used to make Coke or Coking Coal.

COKING COAL, or Metalurgical Coal, is a solid carbonaceous residue derived from low-ash, low-sulfur and low-phosphorus bituminous coal from which the volatile constituents are driven off by baking in an oven without oxygen at temperatures as high as 1,000°C (1,832°F), so the fixed carbon and residual ash are fused together.

STEAM COAL, or Thermal Coal, is a grade between bituminous coal and anthracite coal, once widely used as a fuel for steam locomotives. In this specialized use, it is sometimes known as “sea-coal” in the US.

ANTHRACITE COAL, the highest rank of coal, is a harder, glossy black coal used primarily for residential and commercial space heating.

GRAPHITE, technically the highest ranked coal, is difficult to ignite and is not commonly used as fuel — it is mostly used in pencils and, when powdered, as a “graphite” lubricant.
