No. Anthracite is a purer form of carbon and so, for each unit of heat released, there will be less collateral pollution such as sulphur dioxide.
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.
In terms of impurities the ranking goes like this. Bituminous coal>Anthracite coal>Crude oil>Diesel>Gasoline>Natural Gas>Propane. An example of this is how vehicles in stadiums are powered by propane or nat gas. The more pure the fuel the less carbon monoxide and hazardous chemicals would be produce. You would hardly want to breath the fumes from a coal burning steam engine.
i don't know but i think cars cause more pollution
We can stop the pollution by growing more trees and stoping deforestation
Coal is generally considered a sedimentary rock as it is made up of deposited material (in this case organic matter, mostly from plants) and is eventually covered up by overburden. I'm not going to go into the details of the physical change but the reason black coal might be considered metamorphic is that it has been subjected to more pressure over time which furthers the coalification process. The order of coalification coal: peat -> lignite (brown coal) ->sub bituminous -> bituminous ->anthracite (very rare) everything after lignite is black in colour. If you need this for a report I'd probably look it up though, its been a while since I've studied coal in depth.
i think because sometimes anthracite has more ash and vm than bituminous
Bituminous coal is relatively soft and dull, as opposed to anthracite which is hard and shiny. Anthracite is also much more dense and pure. Because of its purity (can be up to 98% carbon), Anthracite burns a very hot, smokeless flame.
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.
Anthracite coal, it insulates the heat energy better and has more light energy when lit.
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.
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.
Anthracite
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.
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.
this is the order from peat to coal, peat-lignite-bituminous-anthracite- the higher up the the types, the higher BTU burn you well get, as well as a cleaner burn, but it takes more energy to get it started.
According to Energy Information Administration (EIA) research, emissions range from 2,791 lbs per short ton for lignite coal to 5,685 lbs per short ton for anthracite coal. However, the coefficients for the coals that are primarily used in electricity production, bituminous and sub-bituminous are 4,931 and 3,716 respectively. See the EIA related link for more information.
Bituminous sands are oil sands , tar sands and more tecnically they're an unconventional petroleum deposit . I hope I hlped you!!
