What is Lignite?

lignite is a brownish fossil fuel that is used primarily for electricity production. Fuel considered to be a low -floor coal type and geologists have usually categorized as a recent fuel. It is usually suitable among peat and sub-bituminous coal on the steps of geological solid fuel evaluation. Lignite coal is combustible and can also be referred to as brown coal, coal or rosebud.

is geologically considered to be relatively young at age. Some geologists estimate that it created about 251 million years ago, during the Mesozoic and Cellozoic times. It is generally assumed that the fuel was made of peat at shallow depths and at temperatures less than 212 ° F (about 100 ° C). Distinguished plant residues can often be found on brown coal. In addition, the fuel often holds the patterns of the wood from which it was derived.

brown coal has a relatively high content of volatile matter. As a result, the application can be converted into liquid oil more easily than better typescoal such as bituminous coal or anthracite. Fuel is also characterized by a high moisture content, in some cases up to 75%. The Lignite ash content is generally between six and 19%, while its carbon content is about 25%to 30%.

brown coal can be more difficult than other types of coal. For example, it can be prone to spontaneous combustion, which is transport and storage problematic. Due to its limits of transport, brown coal is often burned in a power plant that was set up near the lignite mine. The high content of fuel water also increases the likelihood of disintegration, which further reduces its value. As a result of these restrictions, brown coal is usually not traded on the world market as widely as higher class coal.

There are several main types of brown coal, which are usually ctentorized by a structure. Xyloid coal, also called fossil wood or bituminous wood, has a woolKnita structure of wood. Fiber lignite often looks like peat in appearance and consists of approximately 50% water and 30% ash. On the other hand, Pitchy Lignite is more similar to coal.

Lignite mining occurs around the world throughout Europe, Australia, the United States and Russia. Brown coal production is more common in areas where other types of fuel are rare. Some environmental concerns surround lignite mines because emissions of lignite plant pollution are usually greater than emissions from other types of coal plants.
