The long-chain structure means that polymers can exist in solid or liquid form, but are too large to be volatile. Polymers fuel the vast majority of unwanted fires, as wood, paper, fabrics, foams and plastics. ... cotton, wool etc. Synthetic polymers are generally derived from oil or coal, and share the flammability of those raw materials.

A fine-grained sedimentary rock containing organic material known as kerogen. On distillation, it yields significant amounts of hydrocarbons, including oil. Synfuels. Synthetic fuels, which may be liquid or gaseous, derived from solid fuels, such as oil from kerogen in oil shale, or oil and gas from coal. Shale gas.

Fixed carbon is the solid residue other than ash obtained by prescribed methods of destructive distillation of a coal. Fixed carbon is the part of the total carbon that remains when coal is heated in a closed vessel until all matter is driven off. Floor (coal): The upper surface of the stratum underlying a coal seam.

Fuels are conveniently classified as solid, liquid and gaseous. Solid fuels are sold by weight, liquid and gaseous fuels by volume. We have already discussed charcoal. The other principal solid fuels are coal and coke. Coal is classified by rank. Anthracite contains more than 86% fixed carbon. It is hard, black and dustless.

Andreas Kermann / Getty Images. Magnetite (or lodestone) is a common accessory mineral in coarse-grained igneous rocks and metamorphic rocks. It may be gray-black or have a rusty coating. Crystals are common, with striated faces shaped in octahedrons or dodecahedrons. Look for a black streak and a strong attraction to a magnet.

Coal is a solid but brittle carbonaceous black sedimentary rock that burns. It is made of lesser amounts of sulfur and other trace elements. Coal is divided into four classes: lignite, subbituminous, butuminous and anthracite is the hardest and has the most carbon, giving it a higher hear value. Lignite is the softest coal and has the least ...
