Is coal hard?
Anthracite coal is harder than bituminous coal. Anthracite coal has a relative hardness of 1.3 to 1.4. Bituminous coal has a hardness of less than one.
What is hard coal?
2.2
What are the differences between the types of coal?
Bituminous coal is soft and burns hotter and longer. Anthracite coal is harder than Bituminous coal and is not preferred for heating.
What is harder lignite or anthracite coal?
Anthracite coal is harder than Lignite.
What is the difference between bituminous coal and anthracite coal?
The main difference is the amount of carbon. Anthracite is harder and contains more carbon. Bituminous coal is a sedimentary rock and anthracite coal is actually a metamorphic rock that has undergone tremendous pressures, usually from mountain building events.

Which is better bituminous or anthracite coal?
Anthracite is a better type of coal than bituminous, anthracite is the best type of coal because it is the purest type of coal as it has the highest amount of carbon content present in it. It is made up of 90-95% of carbon content, so, it has a higher calorific value and burns without a smoke. Anthracite is relatively a harder, an older and a purer type of coal as compared to bituminous. Anthracite also burns without a smoke, so it is cleaner and is a more eco-friendly fuel. The only advantage bituminous has over anthracite is that it is present in more quantity than anthracite which is unfortunate because 70-75% of all coals are bituminous and anthracite covers only 5% of all types of coals.
What grade of coal is one step higher in rank than bituminous coal?
anthracite
Why bituminous shows higher calorific value although anthracite is best quality of coal?
i think because sometimes anthracite has more ash and vm than bituminous
Is bituminous coal formed from anthracite coal?
Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen. It is of higher quality than lignite coal but of poorer quality than anthracite. Formation is usually the result of high pressure being exerted on lignite.

What the calorific value of coal?
It varies based on the type and grade of coal. The heat value is less for bituminous than for anthracite, etc.
Which Type of coal is used as household fuel?
Pea coal has been used in household coal stoves for more than a century and a half. It is typically crushed anthracite coal, or sometimes semi-bituminous coal.
Is Bituminous coal more valuable than Anthracite?
Bituminous Coal exists in the geological area known as The Pittsburgh Coal Seam-- an area extending from Western Pennsylvania, Western West Virginia, Ohio, Kentucky, and Indiana. Though mined since the days of Native American Indians, and heavily mined since 1800, it is estimated there is still enough coal in this large seam to last millions of years. Bituminous coal is a soft coal and was well-suited to burning in factories and homes, and thus, held more demand and higher price.
