Coal with very little sulfur content is known as low sulfur coal. This type of coal forms in environments where conditions limit sulfur availability during its formation, such as in freshwater swamps or peat bogs. Lower sulfur content in coal is desirable because sulfur emissions contribute to air pollution and acid rain when coal is burned for energy.
What else can I help you with?
What are the two chemical pollutants that are produced by coal fired power stations?
Most coal burned in power stations contains small amounts of the metal mercury. This metal is released and vaporized as the coal burns. Some coal, particularly lower-quality bituminous coal, contains nitrogen compounds. The nitrogen in this coal (and sometimes nitrogen from the air) combine with oxygen to produce various nitrogen oxides, some of which catalyze the formation of ozone in the lower atmosphere. Most modern coal-fired power stations have very efficient combustion, so they produce very little carbon monoxide, but some older plants produce significant (but still small) quantities. Carbon dioxide isn't universally considered a pollutant, but it is the main combustion product of coal. Some coal contains sulfur or sulfur compounds. These can be released by burning to produce sulfur dioxide, which reacts with water in the atmosphere to produce sulfurous and sulfuric acids, which are significant components of acid rain.
What element is coal made up of?
Coal is primarily composed of carbon, with small amounts of other elements such as hydrogen, oxygen, nitrogen, and sulfur. The presence of these other elements determines the specific type and quality of coal.
Is coal bad for you?
Coal itself is not directly harmful to humans, but burning coal releases pollutants like sulfur dioxide, nitrogen oxides, and particulate matter that can negatively impact human health. Exposure to these pollutants is linked to respiratory issues, cardiovascular problems, and even cancer. Therefore, coal's impact on human health is largely due to the process of burning it for energy.
How easy is it to gain access to coal?
It depends on the depth from surface of the deposit. There are places where coal is naturally exposed at the surface or covered with very little overburden. There are also places where coal is found at relatively great depth.
What is the most common variety of coal?
Probably bituminous, the "middle grade" of coal. Lowest is lignite, which is usually only used in underdeveloped countries as it has low heat output and high pollution. Above bituminous is anthracite, an excellent, very hard (and very expensive) coal. When you ask most people to visualize a lump of coa in their mind, ninety to ninety-five percent of them will visualize bituminous.

Where in England is the most coal mined?
There is very little coal left in England as most of it has already been extracted.
What is mined in Bulgaria?
Mainly coal. Very little copper, zinc and petroleum
Minerals found in Japan?
The minerals that are found in Japan include sulfur, coal, lead, limestone, and zinc. There are not very many mineral deposits in the country.

What is very hard rock that burns with a high heat and little smoke formed from granite?
The rock you are referring to is anthracite coal. It is a type of coal that is very dense, high in carbon, and burns with a clean, hot flame. Anthracite coal is formed from the metamorphism of sedimentary rock, such as bituminous coal, over millions of years.
Why don't many power companies want to make the change from coal to other sources of energy?
Coal is a low cost, abundant fuel. It is estimated that at our current rate of usage we have over two hundred years of coal reserves. Coal has also become a very clean burning fuel with the recent development of sulfur removal methods.
What is A very hard rock that burns with high heat and little smoke made formed from coal?
anthracite
Is coal a good fuel?
Coal is a convenient, low cost fuel. However, coal is also dirty, producing air borne particulate matter and numerous dangerous compounds. Acid rain is a result of the burning of high sulfur coal. Coal often contains heavy metals that are extremely hazardous to life. New generation coal fired power plants are much cleaner, but very expensive and rarely required by environmental laws in the US.

What does coal do to damage the environment?
Coal is a chemically complex fuel. Whenever it is burned, gases are given off and particles of ash, called "fly ash," are released. The sulfur in coal combines with oxygen to form sulfur dioxide, which can be a major source of air pollution if emitted in large enough quantities. It can affect people breathing problems and be very dangerous in the future
