Question

Which type of Coal is the best quality of Coal?
A.Peat
B.Lignite
C.Anthracite
D.None of these

Answer 1

Hint:The carbon content of this type of coal is between 86 percent and 98 percent. It burns with short, blue, and smokeless flames, however, it ignites with difficulty. The moisture content of this type of freshly mined coal is normally less than 15 percent.

Complete answer:
Coal is a combustible sedimentary rock, black or brownish-black, formed as rock strata called coal seams. Coal is primarily carbon with varying quantities of other ingredients, mostly hydrogen, oxygen, nitrogen, and sulphur.

Anthracite is a hard, compact type of coal that has a sub-metallic lustre, and is also referred to as “hard coal”. Of all types of coal, it has the highest carbon content, the lowest impurities, and the highest energy density, and is the highest category of coal. The term “anthracite” is applied to those varieties of coal that do not give off tarry or other hydrocarbon vapours when heated below their ignition point .

Anthracite coal of normal grade is primarily used in power generation, and high grade (HG) and ultra-high grade (UHG), the main uses of which are in the metallurgical industry. Around 1% of global coal reserves are accounted for anthracite.

Anthracite is mined in just a few countries around the world. China accounts for the bulk of global output; Russia, Ukraine, North Korea, South Africa, Vietnam, the United Kingdom, Australia, Canada, and the United States are other producers.

Hence, the correct answer is option (C).

Note: The type of coal discovered in India is bituminous. It is a medium grade of coal with a high potential for heating. It is India's most widely used form of coal for electricity generation. The greater number of bituminous coal is found in Jharkhand, Odisha, West Bengal, Chhattisgarh, and Madhya Pradesh.
