- Solid fuel
Solid fuel refers to various types of
solid material that are used asfuel to produceenergy and provideheating , usually released throughcombustion .Solid fuels include
wood (seewood fuel ),charcoal ,peat ,coal ,Hexamine fuel tablet s, and pellets made from wood (seewood pellets ),corn ,wheat ,rye and other grains.Solid-fuel rocket technology also uses solid fuel (see solid propellants).Solid fuels have long been used by humanity to create fire. Coal was the fuel source which enabled the
industrial revolution , from firingfurnace s, to runningsteam engine s. Wood was also extensively used to runsteam locomotive s. Both peat and coal are still used inelectricity generation today.The use of some solid fuels (eg. coal) is restricted or prohibited in some
urban area s, 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. In some areas, smokeless coal is often the only solid fuel used. In Ireland, peatbriquette s are used as smokeless fuel. They are also used to start a coal fire.ee also
