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. The principal use of anthracite today is for domestic fuel in either hand-fired stoves or automatic stoker furnaces. It delivers high energy per its weight and burns cleanly with little soot, making it ideal for this purpose. Its high value makes it prohibitively expensive for power plant use. Due to fewer impurities and the highest calorific value, the global demand for anthracite has increased, increasing the anthracite mining market. Compared with other coal types, anthracite has less residue and impurities after combustion, and the flue gas is negligible, making it an efficient fuel. MOQ: 25,000 MT Supplied from Indonesia, Australia, and Russia.

Coal is a sedimentary deposit composed predominantly of carbon that is readily combustible. Coal is black or brownish-black, and has a composition that (including inherent moisture) consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material. Coal is primarily used as fuel to generate electric power all over the world. In coal-fired power plants, bituminous coal, sub-bituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity. The ranks of coals, from those with the least carbon to those with the most carbon, are lignite, sub-bituminous, bituminous, and anthracite. MOQ : 30,000 MT Supplied from Indonesia.

coal, one of the most important primary fossil fuels, a solid carbon-rich material that is usually brown or black and most often occurs in stratified sedimentary deposits. We are Supplying Indonesia and Africa mined Coal . We can Supply Type 1 to Type 7 Gross Calorific Value ( 6,500 6,300 6,000 5,800 5,500 5,300 5100 and below)

Color Black or brown, varying shades Texture Can be smooth, granular, or banded Hardness Soft to hard, depending on coal type Luster Dull to shiny Density Varies depending on coal type, typically around 1.2-1.5 g/cm�³ Porosity Varies, can be porous Composition Mainly composed of carbon, along with hydrogen, sulfur, oxygen, and trace minerals Moisture Content Can range from a few percent to over 30% Volatile Matter Varies, typically 20-45% Fixed Carbon Varies, typically 40-90% Ash Content Varies, typically 3-30% Heating Value (BTU/lb) Varies depending on coal type, typically 8,000-14,000 BTU/lb Heating Value (MJ/kg) Varies depending on coal type, typically 24-33 MJ/kg Combustion Characteristics Burns to release heat, producing carbon dioxide and other gases

Steam coal, also called thermal coal, refers to the coal used in boilers to produce steam that can be used for various purposes. Steam coal is a derivative of coal, as a black stone that burns when exposed to high heat. Coal is used throughout the world today as a primary source of energy and is naturally found as sedimentary rock The types of coal that we can supply are 5 types according to the Indonesian Coal Index (ICI), namely as follows: ICI-1 â?¢ GAR : 6500 â?¢ NAR : 6200 â?¢ Sulfur : Up to 1% â?¢ Ash : Up to 12% â?¢ Total Moisture : Up to 12% ICI-2 â?¢ GAR : 5800 â?¢ NAR : 5500 â?¢ Sulfur : Up to 0.8% â?¢ Ash : Up to 10% â?¢ Total Moisture : Up to 18% ICI-3 â?¢ GAR : 5000 â?¢ NAR : 4600 â?¢ Sulfur : Up to 0.6% â?¢ Ash : Up to 8% â?¢ Total Moisture : Up to 30% ICI-4 â?¢ GAR : 4200 â?¢ NAR : 3800 â?¢ Sulfur : Up to 0.4% â?¢ Ash : Up to 6% â?¢ Total Moisture : Up to 40% ICI-5 â?¢ GAR : 3400 â?¢ NAR : 3000 â?¢ Sulfur : Up to 0.2% â?¢ Ash : Up to 4% â?¢ Total Moisture : Up to 50%
