Introduction to coal
The main components in coal are carbon, hydrogen, oxygen and little nitrogen, sulfur as well as others. Sulfur is the major foreign matter in coal and it often takes the form of sulfide to exist in burning products of coal. Coal resource is very rich in the world. Demand and supply are stable, so the coal price is cheaper than that of oil and gas.
Coal uses
Coal is used for coking work, which can produce coal tar and ammonium hydroxide. Coked coal is the important raw material for iron making. Many people think that coal gas is produced from coal. But, actually, coal gas is produced from the naphtha, which is refined from raw oil. Coal can be directly vaporized to make water gas, which is used as clean fuel.
Customer case
This customer comes from India and he owns a coal mine. After long time production, he think the cost is high. So, he asks Fote specialists for technological upgrade. The current problem is that cost wof briquetting work takes 70% in the total cost. So, Fote specialists mainly study the briquetting part in the coal mining work. By using the Fote upgraded briquetting plant for half a month, the production cost is remarkably decreased.
