The Differences between Bituminous Coal and Anthracite Coal

Sep 28,  · The key difference between anthracite and coal is that anthracite has a higher quality when compared to normal coal. Moreover, compared to other normal coal, anthracite is harder, produces more energy when burned, does not ignite easily, impurities are less, and has higher carbon percentage. Another important difference between anthracite and coal is that anthracite occurs as . Sep 28,  · Bituminous coal contains % carbon, whereas anthracite coal contains more than 87% carbon. • Bituminous coal can be converted to anthracite with time. This process is known as anthracitization. • Bituminous coal is a sedimentary rock, whereas anthracite is a metamorphic rock.

Sometimes we would what is the meaning of goitre coal, sometimes coke, and sometimes anthracite. There's an open fire where I live now and we get our coal in nice little bags from the local garage. But all they have is coal. No coke or anthracite. I wonder if this would be better placed in Geology [ ]. I should have made it clearer that what I was asking is what is the difference between using the different types as fuel for an open fire.

Coke and anthracite are smokeless fuelssome types of coal are not smokeless. Spotted this photo of a Chinese coal delivery The briquettes are formed from coal dust as, I believe, was Anthracite and probably Phurnacite and Ancit.

I use something similar to get our open fire up to heat - then we burn logs for the rest of the evening. The gas was produced by distilling coal and separating the products: gas, tar oil and coke which still had a relatively high calorific value. The tar oil would be further distilled in a fractionating tower to produce fine chemicals such as naphthalene, pyridine etc down to the heavier fractions and heavy oils like creosote. The final product would be coal tar that was used for road building.

As a chemistry student I was shown around one of these places in Scunthorpe - as I was working in sugar manufacture the differences were amazing. My dad used to collect coke, free of charge, from the Plymouth Gasworks.

He had to take his own sacks, though. This was in the early nineteen fifties. I'm alien to all this, where I come from it would be daft to heat a house, and coke is something we drink along with a bit of rum. What do you mean by coke? Pages: [ 1 ] Go Up. Similar topics 5.

What is Anthracite?

By definition, bituminous coal contains less than 86 percent fixed carbon while anthracite contains 86 percent or more fixed carbon. Because of the difference in their relative levels of carbon, each of these types of coal is used very differently. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter. Anthracite is not as commonly mined as other ranks of coal. It played a significant role in Pennsylvania coal during the Industrial Revolution in the United. Anthracite coal is commonly called metallurgical coal. datingesk.com hotter is cleaner and is used for steel making coking operations. We export alot as global demand high still. Bituminous coal is more common. Has different grades in respect to BTU content. All less than Anthracite. It .

Anthracite Coal vs Bituminous Coal. Coal is a fossil fuel similar to natural gas and oil, which is in a solid rock form. Coal is formed by collecting plant debris in swamps. The process takes thousands of years. When plant materials collect on swamps, they degrade extremely slowly.

Normally swamp water does not have a higher oxygen concentration; therefore, microorganism density is low there, resulting in minimum degradation by microorganisms.

Plant debris accumulates in swamps because of this slow decaying. When these are buried under sand or mud, the pressure and inside temperature convert the plant debris to coal slowly. To accumulate a large number of plant debris and for decaying process, it takes a long time. Further, there should be suitable water levels and conditions to make this favorable. Thus, coal is considered as a non renewable natural resource.

This is because, when coal is mined out and used, they cannot be regenerated again easily. There are different types of coal. They are ranked based on their properties and composition. Such coal types are peat, lignite, sub bituminous, bituminous and anthracite. Anthracite is a type of coal as stated above. Among the other types, this has a higher ranking due to its remarkable properties. Anthracite processes a higher amount of heat per unit mass than the other types of coal.

It does not ignite easily, but when it does a blue, smokeless flame is produced for a short time. Anthracite is harder than other coal types; therefore, it is known as hard coal. Other types of coals are considered as sedimentary rocks, whereas anthracite is metamorphic. Anthracite is formed when other lower ranked coal types are subjected to higher temperature over a long period of time.

Anthracite is relatively rare and available in a small amount in Pennsylvania, America. Bituminous coal is the most abundant type coal.

It is soft and contains a substance called bitumen, which is similar to tar. And there is water, hydrogen, sulfur and few other impurities. This can be categorized into three as low volatile bituminous, medium volatile bituminous and high volatile bituminous, based on their volatile content. Bituminous coal is produced from sub bituminous coal when it undergoes more organic metamorphism.

What is the difference between Anthracite and Bituminous Coal? For example, anthracite is harder, produces more energy when burned, does not ignite easily, have a low amount of impurities and a higher carbon percentage compared to bituminous coal.
