Question

briefly describe about :
a. Peat
b. Lignite
c. Bituminous coal
d. Anthracite...​

Answer 1

Answer:

PEAT - It contains up to 90% of moisture and is not attractive as a utility fuel.

LIGNITE - It is the lowest grade of coal containing moisture as high as 30% and high volatile matter.

BITUMINOUS - It contains 46–86% of fixed carbon and 20–40% of volatile matter. Lower the volatility higher the heating value.

ANTHRACITE - It contains more than 86% fixed carbon and less volatile matter, Volatile matter helps in the ignition of coal. So it is often difficult to burn anthracite.
