write a short note about bituminous and Lignite coal
Answers
Answer:
Bituminous coal is a middle rank coal between sub bituminous and anthracite. Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Lignite has a low heating value and a high moisture content and is mainly used in electricity generation.
Explanation:
Answer:
Bituminous:- Bitumen meaning is a low-grade crude oil that is made up of complex, heavy hydrocarbons in basic terms. Bitumen is a dense, viscous substance that must be drained from the earth in an oil reservoir. To upgrade it to a better product, a lot of heat and effort must be used when extracting it.
Lignite coal:- It is soft brownish coal formed from naturally compressed peat at shallow areas having temperatures lower than 100°C. Brown coal is generally combustible in nature and is often formed as a sedimentary rock. Due to its low heat content, lignite is considered the lowest rank of coal and is often found to contain recognizable plant fossils.
