Question

Give geographical reasons why: Anthracite is used for domestic purposes.

Answer 1

Hint: The most metamorphosed form of coal is anthracite, commonly known as hard coal. It has more fixed carbon and less volatile matter than any other type of coal and it has calorific values close to 35 megajoules per kilograms, which are similar to those of most bituminous coal.

Complete answer:
Anthracite coal is the least common type of coal. Anthracites have a bright, almost metallic sheen and range in colour from black to steel grey. They can be polished and used for ornamentation. Anthracites are hard and brittle, and they break into sharp fragments with a conchoidal fracture. They are pure to the touch, unlike many bituminous coals.

Anthracites are difficult to ignite, but once ignited, they burn with a pale blue flame that requires minimal maintenance to keep going. Because of its scarcity and relatively expensive cost, as well as the readily available alternative energy sources, such as natural gas and electricity for heating, anthracite is rarely used for this purpose today.

Today, anthracite is primarily used as a residential fuel in hand-fired stoves or mechanical stoker furnaces. It provides a lot of energy for its weight and burns cleanly with little soot, so it's perfect for this. Its high cost renders it unsuitable for use in power plants. The fine particles are also utilized as filter media and as a component in charcoal briquettes.

Thus Anthracite is utilized for domestic purposes because it produces less smoke and contains more than 90% carbon.

Note: Anthracite is used in the home because it has high carbon content and is environmentally beneficial. Because they make minimal dust when handled, burn slowly, and release relatively little smoke, they were sometimes employed for residential heating.
