Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Smokeless fuels typically last as much as 40% longer than coal, producing 20% less CO2 in the process. Heating efficiency is also increased. Multifuel stoves have a 65% better heat output with smokeless coal, compared to the 28% output achieved by older house coal. The high efficiency of modern smokeless coal means customers spend less time ...

Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total global coal production.

Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal ), and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer.

Coalite is a brand of lowtemperature coke used as a smokeless fuel. The title refers to the residue left behind when coal is carbonised at 640 °C (1,184 °F). It was invented by Thomas Parker in 1904. In 1936 the Smoke Abatement Society awarded its inventor a posthumous gold medal. Coalite is darker and more friable than high temperature coke.
