Question

Identify the type of coal that has the highest calorific value.

Options

• Peat

• Lignite

• Bituminous

• Anthracite

Answer 1

Anthracite

Explanation:

Anthracite has the highest carbon content (90%), is the hardest, burns with maximum heat and minimal smoke, and therefore possesses the highest calorific value among peat, lignite and bituminous coals. It is preferred for domestic use and metallurgical processes due to its high energy density.
