By reducution of coal do you mean reducing the use of coal , or obtaining the chemicals from it.
By reducing the use of coal you can use, wind, water, sunlight, nuclear to produce power.
However, coal can baked in coke ovens to reduce it to coke(impure carbon), together with gases given off, such as carbon dioxide, sulphur dioxide, ammonia, hydrogen sulphide. These gases can be used industrially to make other things.
Methane!!!!
However, have an expression for a collection of dangerous gases.. It is called 'Fire Damp'.
Fire Damp is a mixture of methane, coal dust and oxygen. It will readily ignite and flash through the mine, and is extremely dangerous. Anything that it likely to make a spark, matches, cigarette lighters, watches, jewellery, rings etc., are NOT allowed down coal mines, simply because they may spark and thereby the possibility of ignition and a flash.
Mining Engineers and 'Deputies' regularly test for 'Fire Damp'. A very old fashioned method , but also very reliable, is to take a canary(sinnig bird), into the region of the mine were it is suspected. If the canary looks as though it is going to fall off its perch or becomes unconcious, then there is Fire Damp. To remove clean air is pumped through the mine.
NB The bird will not be killed if quickly removed to a more oxygenated region, where it will recover.
NNB Coal miners often bred canaries, for this purpose and to hear their song.
Anthracite coal has the highest percentage of carbon among the different types of coal.
As an industrial chemical.
Used to heat boilers for electric generation.
The gases given off when combusted, can be collected and used in further chemical manufacture. These gases are Carbon dioxide, Ammonia, Sulphur Dioxide, Methane, Hydrogen sulphide.
Coal is a compound and a mixture.
It is a Black Shiny rock.
Its principal elements is CARBON. , but since it is compressed organic matter it will contain Hydrogen, Oxygen, Nitrogen, Sulphur.
Coal is mined and then heated in COKE OVENS. This gives an impure form of carbon. The other compounds given off, are Carbon Dioxide, Water, Methane, Ammonia, sulphur dioxide, Hydrogen Sulphide. All these gases are captured and put to use to make other chemicals.
Alp u know the answer. anyway its called turbine.
It is NOT purified, but baked in coke ovens.
When baked the residue is 'coke' An impure form of carbon.
Gases are liberated too!!!!
They are carbon dioxide, sulphur dioxide, Ammonia, hydrogen sulphide, methane.
These gases are collected, not released into the atmosphere, and industrial use is made of them .
For heating. !!!!
Also it is an industrial chemical, which is baked to form coke, and liberates , ammonia, hydrogen sulphide, methane, sulphur dioxide, which are collected and further used industrially,.
Thermal energy, to provide heat for steam making in power stations.
Also to provide chemicals for making fertilisers, sulphuric acid, coke for iron ore reduction.
It is not a mineral .
However, in a different sense it is a mineral, because it is mined.
It is from the carbonaceous group.
No, coal is not a mineral because a mineral has to be inorganic meaning that it can not be made by a life process.
Coal mining can do alot to the enviroment. Coal mining can pollute the air, and destroy habitats like forests and wetlands. Coal mining can do alot to the enviroment. Coal mining can pollute the air, and destroy habitats like forests and wetlands.
It consists primarily of carbon, but contains other elements. There are different types of coal, which have different compounds. See link.
Coal is an impure form of carbon.
When combusted it releases carbon dioxide. . It also releases , sulphur dioxide, ammonia, hydrogen sulphide. These three gases are released in much smaller quantities.
In modern coal fired power stations, 'scrubbers' or varying types are placed in the exhaust flue(chimney), in order that they can be used elsewhere.
So when viewing a power station from the outside, if the coal is being combusted correctly, you will not see any smoke from the chimney. However, there are usually large cooling towers alongside a power station, issuing 'white smoke'. This 'White smoke' is actually 'steam', that has not fully condensed in the cooling tower.
A boiler in a coal power station is responsible for converting water into steam. The coal is burned in the furnace of the boiler, producing heat which is used to generate steam. This steam is then used to drive a turbine, which spins a generator to produce electricity.
Burning coal emits toxic and carcinogenic substances into our air, water and land, severely affecting the health of miners, workers and surrounding communities.
Rotting vegetation is overlaid by more rotting vegetation or other material.
This is compressed by the mass above and form peat.
Compression of the peat continues and form lignite (brown coal)
Compression continues on the lignite to form coal (clack shiny rock)
Compression may continue to form anthracite , the hardest form of coal .
NB with each compression watert/moisture is expelled, so coal and anthracite are very dry.
Coal is mostly carbon, but often has impurities of sulfur and several other elements. It also doesn't have an exact and universal chemical formula, so no, there is no chemical name for coal.
I agree with your correspondent 'Wiki User'.
Coal is being formed today.
Its first stage is peat formation, found on moorlands in the UK.
As more material lies over it, it becomes compressed and begins to fry out. At this stage it is lignite.
Continued compression changes the lignite into coal, a black bright shiny carboniferous rock.
Continued compression the coal becomes anthracite. A very hard bright coal, that burns with a hot flame.
Coal still in the ground is remains named as 'coal'. It is a carboniferous rock.
