The amount of sulphur in coal is directly related to the amount of sulphur dioxide it would produce on burning and hence it becomes necessary to check sulphur content since there are emission limits on amount of sulphur dioxides that can come out since it is an air pollutant.
To remove sulphur one might consider adding carbonates as it would help convert sulphur dioxide to sulphates which can be removed along with the ash.

Why is sulfur an undesireable part of coal?
Sulfur is an undesirable constituent of coal because the primary use of coal is burning the coal to supply energy. Any sulfur present in the coal is usually converted, when the coal is burned, into an oxide of sulfur that can acidify rain water when it escapes into the atmosphere.
Element that is a yellow solid found as an impurity in coal?
An element that is a yellow solid and found as an impurity in coal is sulfur. Sulfur is one reason why burning coal creates pollution. When impure coal is burned, sulfur dioxide is created and contributes to phenomena such as acid rain.
What is a cause of acid rain from burning coal?
All coal has some amount of sulfur in it. The sulfur burns into sulfur dioxide, which reacts with water to make sulfurous acid in the rain.
When coal containing sulfur is burned sulfur is converted to what?
solid sulfur oxides that stay behind as ash.
Why are enviromentalists angry about coal with a high sulfur content?
Burning sulfur = CO2
Is sulfur a type of coal?
No. Coal is mostly carbon. Sulfur is an element that may be found in some types of coal, but it is not coal.

Burning high sulfur coal?
sulfur oxide
What does burning high sulfur coal produce?
Sulfur oxides
What is the cause of sulfur oxide?
The burning of coal that contains a lot of sulfur.
Element that is a yellow solid found as an impurity in coal?
An element that is a yellow solid and found as an impurity in coal is sulfur. Sulfur is one reason why burning coal creates pollution. When impure coal is burned, sulfur dioxide is created and contributes to phenomena such as acid rain.
What percentage of sulfur is in coal?
2 %
What is a cause of acid rain from burning coal?
All coal has some amount of sulfur in it. The sulfur burns into sulfur dioxide, which reacts with water to make sulfurous acid in the rain.
What has the author R A Chapman written?
R. A Chapman has written: 'Coal resources and sulfur emissions regulations' -- subject(s): Coal, Coal mines and mining, Coal reserves, Sulfur content, Desulfurization
When coal containing sulfur is burned sulfur is converted to what?
solid sulfur oxides that stay behind as ash.
Why are enviromentalists angry about coal with a high sulfur content?
Burning sulfur = CO2
How is pounds of sulfur dioxide per million BTU of coal calculated?
The sulfur content of coal and its heating values are not constant across all grades of coal. It would require information of type of coal, carbon content, sulfur content and ash content to even start the calculation.
