Question

Anthracite is ideal for domestic use as:

Options

• It has high calorific value

• It has more carbon content

• It does not produce smoke nor ash

• All the above

Answer 1

All the above

Explanation:

Anthracite is uniquely suited for residential use because it possesses a very high carbon content (over 85-90%) which directly results in a high calorific value, generating maximum heat energy. Furthermore, due to its low volatile matter and high purity, it burns cleanly with a steady blue flame and does not produce smoke, soot, or substantial ash, making it the cleanest-burning and safest option for indoor heating.
