Solid fuel refers to various types of solid materials that are used as fuel to produce energy and provide heating.
Solid fuels include wood, charcoal, peat, coal, Hexamine fuel tablets, and pellets or briquettes made from wood, corn, wheat, rye and other grains (biomass).
Solid fuels have been used by humanity for many years to create fire. Coal was the fuel source which enabled the industrial revolution, from firing furnaces, to running steam engines. Wood was also extensively used to run steam locomotives. Both peat and coal are still used in electricity generation today.
The use of some solid fuels (eg. coal) is restricted or prohibited in some urban areas, due to unsafe levels of toxic emissions. The use of other solid fuels such as wood is increasing as heating technology and the availability of good quality fuel improves.
