Before the coal is burned, it is pulverized to the fineness of talcum powder. It is then mixed with hot air and blown into the firebox of the boiler. Burning in suspension, the coal/air mixture provides the most complete combustion and maximum heat possible.
Anthracite coal is a form of coal that is almost made entirely of carbon. Anthracite coal is much harder than other forms of coal such as bituminous, and is usually found in areas surrounding mountains or deep valleys.Anthracite burns much cleaner than other forms of coal due to its low pollutant content.nthracite coal is the cleanest form of coal as it produces very little pollution and does not stain skin when touched, unlike most forms of coal.
