Anthracite, bituminous, lignite and peat are different types of
Hint: Anthracite, bituminous, lignite and peat are also called black gold and are found in the sedimentary layers of soil Complete Answer: Anthracite, bituminous, lignite and peat are different types of coal Coal is a solid fossil fuel which contains volatile matter, carbon, moisture and ash or in some cases phosphorus and sulphurgrinding lignite with feed moistures of as much as 45 % Depending on this high feed moisture the mill rating is determined by the drying process whereas for anthracite, hard coal and petcok e the rating of the mill is determined by the grinding process The great variety of solid fuel properties,Reprint from ZKG 3 Gebr PfeifferCompared with the commonly studied anthracite, lignite suffers from low coalification degree, low heat, high volatile components, high moisture, and ease of spontaneous combustion, resulting in it being regarded as an inferior fuel [17] Besides, the graphitization of lignite is difficult even at high temperatures up to 3000 C [18,19]Study on Structural Evolution of Synthetic Graphite Derived from Peat, lignite, bituminous, and anthracite are all different forms of coal Lignite Uses There can be numerous uses of lignite coal, and the most commonly seen is the fossil fuel power plant Since lignite contains high amounts of volatile substances, it can easily be converted into liquid and gas forms, such as petroleum productsLignite Types, Characteristics, Uses, Applications and Facts
