A method of reducing sulphur dioxide emissions from coal by adding an effective amount of Wyoming Trona to the coal for combining with sulphur in the coal to form a relatively heavy ash which is collected with other heavier ash for removal in the usual way.
Removal of sulphur from coal by air oxidation at 350–450
The amount of organic sulphur removed was estimated as equal to the weight loss of the coal (other than sulphur) times the fraction of the coal which was organic sulphur. This assumes that removal of organic sulphur is contingent upon removal of volatile matter and carbon gasifiion.

It is abundant, multivalent, and nonmetallic.Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S 8.Elemental sulfur is a bright yellow, crystalline solid at room temperature.
Why do you analyze sulfur in coal Answers
Coal has quite a significant nitrogen content (often around 1.5% by weight), and when burned it reacts with oxygen in the air under high heat (typically more than 1500 degrees F) to form nitrogen
