Is bituminous coal is metallurgical or steam coal?
Bituminous coal can be used for both metallurgical and steam coal applications. Metallurgical coal is used in the steelmaking process to help create coke, while steam coal is used as a fuel source for generating electricity.
What is bituminous coals relative hardness?
Bituminous coal has a relative hardness of around 2-2.5 on the Mohs scale, which measures the hardness of minerals based on their ability to scratch another material. This places bituminous coal at a moderate hardness level compared to other minerals.
What is bituminous coal used for?
The bituminous coals are considered to be 'all purpose' coals,and because of its excellent heating quality and the ease with which it can be handled, it is the most extensively used fuel in the world. In inditries it can be used for steam raising ,heating purposes, gasification, and coking
How to calculate ncv from gcv of coal?
Net calorific value (NCV) can be calculated from gross calorific value (GCV) of coal using the formula: NCV = GCV - (0.09 * moisture content) for lignite and sub-bituminous coals, or NCV = GCV - (0.07 * moisture content) for bituminous and anthracite coals. The moisture content is usually provided on the coal analysis sheet.
Colors of bituminous coal?
The colour of the bituminous coal varies from pitch black to grey colour. Sometimes more or less laminated showing layers of bright and dull coals

Is bituminous coal safe to cook with?
Bituminous coals are not very much safer for the cooking purposes as it gives smoky flames which may cause many health hazards
What is coals cleavage?
Coal does not exhibit cleavage because it is a sedimentary rock composed mainly of carbon and does not have a crystalline structure like minerals with cleavage. Instead, coal fractures irregularly along its layers or bedding planes.

What does bituminous mean?
Bituminous refers to bitumen, the more fluid tarry substances or bitumen that is found in some coals and which may be distilled off as coal tar. Hard dry coals are called anthracite because of its stony nature.
What has the author E J Hippo written?

Why have anthracite mining rates declined?
Most of the original markets for anthracite were relinquished long ago to natural gas, fuel oil, and other coals, such as bituminous and lignite coal.
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.
