What is Coal? Indiana Coal Characteristics. Coal is generally characterized and priced based upon its different characteristics Some of the most common are: BTUs—how hot does it burn. Indiana coal provides good heat value; 10,500-12,000 BTUs/lb. Moisture Content—the amount of water reduces the fuel or burning power, and can generate excess ...
The higher the number of BTUs, the more heat is produced. Lignite has a lower BTU level than any other type of coal; therefore, it burns faster and contains less heat energy than harder coals (anthracite, bituminous, and subbituminous).

4 Coal Fossil Energy Study Guide: Coal STONE AGE It is believed coal was used for heating and cooking. 100 – 200 AD The Romans use coal for heating. 1300S In the U.S. southwest, Hopi Indians use coal for heating. 1673 Explorers to the United States discover coal. 1700S The English find coal produces a fuel that burns cleaner and hotter than wood charcoal. ...
Sep 28, 2011· Thus, coal is considered as a non renewable natural resource. This is because, when coal is mined out and used, they cannot be regenerated again easily. There are different types of coal. They are ranked based on their properties and composition. Such coal types are peat, lignite, sub bituminous, bituminous and anthracite. Anthracite Coal
86% and 98% carbon by weight, & it burns slowly, with a pale blue flame & very little smoke Bituminous coal (in Indiana), contains between 69% & 86% carbon by weight Sub-bituminous coal contains less carbon, more water & is a less efficient source of heat Lignite coal, or brown coal, is a very soft coal that contains up to 70% water by weight ...
Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt. It is of higher quality than lignite coal but of poorer quality than anthracite. Formation is usually the result of high pressure being exerted on lignite.
Dec 30, 2008· I think I found one more piece of the puzzle. The coal I got (free for the hauling) is a random mixture of all sizes, from dust to the size of my fist. I tried just putting in the chestnut sized coal and it seems to burn much hotter. My theory is that more air can pass through the coal bed, thus burning hotter. I'm not sure if I'm right or not.
The Xcel Energy (formerly Northern States Power) Sherco Plant, located in Becker, Minn., is a coal-fired facility that burns a low-sulfur, sub-bituminous coal from Wyoming and Montana. This plant, Xcel's largest, was the site were the wet precipitator process within a scrubber system was pioneered - a process that removes more particles and ...
Subbituminous coals have higher moisture and volatile matter and lower sulfur content than bituminous coals and may be used as an alternative fuel in some boilers originally designed to burn bituminous coals. 1 Generally, bituminous coals have heating values of 10,500 to 14,000 British thermal units per
Mar 15, 2019· Sub-bituminous coal is considered black coal, even though its appearance varies from bright black to dull dark brown. Its consistency ranges from hard and strong to soft and brittle due to its intermediate stage—between bituminous and brown coal (lignite). The coal is widely used for generating steam power and industrial purposes.
Jan 25, 2016· Coal – Formation of Coal – Types of Coal – Peat, Lignite, Bituminous Coal & Anthracite Coal. Carbon content in different types of coal. Importance of each type. Coal Also called black gold. Found in sedimentary strata . Contains carbon, volatile matter, moisture and ash Mostly used for power generation and metallurgy. Coal reserves are six times greater than oil and petroleum .
Anthracite, a hard black coal that burns with little flame and smoke, has the... Get Price. Sub-bituminous coal - Using Bituminous Coal - Anthracite Coal Forum. Ive tried to find as much info about sub-bituminous coal and the kind of ... expect it would be very sooty and smokey until the volitiles burn .
The coal is slow-burning and difficult to ignite because of its high density, so few pulverized, coal-fired plants burn it. Heating Value . Anthracite burns the hottest among coal types (roughly 900 degrees or higher) and typically produces approximately 13,000 to 15,000 Btu per pound. Waste coal discarded during anthracite mining, called culm ...
Apr 16, 2018· Burning coal for heat can be an excellent choice if done safely. The highest-quality coal, known as anthracite, is available for purchase and can be used in many coal-burning stoves, heaters and boilers. Coal heat has drawbacks, however, as well as .
Burning Coal Beginning in late 1979 the word coal started to again become popular with consumers. Rumors that we would run out of wood and those saying that we have an almost inexhaustible supply of coal probably had something to do with it.
Characteristics of Coal The characteristics of coals that determine classification and suitability for given applications are the proportions of : 1. volatile matter 2. fixed carbon 3. moisture 4 ...
Coal is formed as part of a very long process. Younger coal or coal where the process has been slower is different from ancient coal. Generally the older it is, the cleaner it burns. Some types are: lignite, subbituminous coal, anthracite, and bituminous coal
Lignite, subbituminous coal, bituminous coal, and anthracie. They are formed when peat is compressed and water squeezes out. Gases escape and carbon increases. As the carbon increases, the peat turns into lignite, then subbituminous coal, and bituminous coal. These are all sedimentary rocks. Anthracite, a metamorphic rock, is formed last.
1.1 Bituminous And Subbituminous Coal Combustion 1.1.1 General Coal is a complex combination of organic matter and inorganic mineral matter formed over eons from successive layers of fallen vegetation. Coals are classified by rank according to their progressive alteration in the natural metamorphosis from lignite to anthracite. Coal rank depends on
Sub-bituminous coal or black lignite is a category of coal which appears as grey-black or dark brown. It ranges from hard to soft as it represents an intermediate stage between low quality lignite and higher quality bituminous coal. The carbon content of sub-bituminous coal varies from 70-76%.
Oct 02, 2017· For coal, washing removes a little of the sulfur, but most stays with the coal and is removed afterward if it is a highsulfur coal (, Illinois bituminous) or emitted to the atmosphere if it is a lowenough sulfur coal, like subbituminous coal...
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat.It is considered the lowest rank of coal due to its relatively low heat content.It has a carbon content around 60–70 percent. It is mined all around the world, is used almost exclusively as a fuel for steam-electric power generation, and is the coal which is most ...
Coal is not only our most abundant fossil fuel, it is also the one with perhaps the longest history.
