ANTRACITE COAL:

Anthracite is a hard, compact variety of mineral coal which is highly lustrous. It has the highest carbon content, the fewest impurities, and the highest calorific content of all types of coal, including bituminous and lignite coal. Anthracite is the most metamorphosed type of coal, wherein the carbon content ranges from *2.1% to *8%. The term is applied to those verities of coal which do not give off tarry or other hydrocarbon vapors when heated below their point of ignition. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation. High grade (HG) and Ultra High Grade (UHG), the principal uses of which in the metallurgy sector.

PINE WOOD

Pines are among the most commercially important tree species valued for their timber and wood pulp throughout the world.In temperate and tropical regions, they are fast-growing softwoods that grow in relatively dense stands, their acidic decaying needles inhibiting the sprouting of competing hardwoods. Commercial pines are grown in plantations for timber that is denser and therefore more durable than spruce (Picea). Pine wood is widely used in high-value carpentry items such as furniture, window frames, paneling, floors, and roofing, and the resin of some species is an important source of turpentine.

Because pines have no insect- or decay-resistant qualities after logging, untreated they are generally recommended for construction purposes as indoor use only (indoor drywall framing, for example). For outside use, pine needs to be treated with copper azole, chromated copper arsenate or other suitable chemical preservative.
