Why is Gondwana coal preferred over Tertiary coal?
This coal is free from moisture and contains sulphur and phosphorus in small variable quantities. This coal has a higher moisture content and more sulphur with less calorific value.
Which coal will have highest ash content?
Coking coal– the carbon content is around 43%-86%. It is a type of bituminous coal. Hence lignite has the least carbon content which means that it has the highest ash content.
What is yellow coal?
lignite generally yellow to dark brown or rarely black coal that formed from peat at shallow depths and temperatures lower than 100 °C (212 °F). It is the first product of coalification and is intermediate between peat and subbituminous coal according to the coal classification used in the United States and Canada.
