Smokeless fuel

Smokeless fuel is a type of solid fuel which either does not emit visible smoke or emits minimal amounts during combustion. These types of fuel find use where the use of fuels which produce smoke, such as coal and unseasoned or wet wood, is prohibited.

As a result of many places banning smoke and pollution, studies have shown that overall air quality improved, and there were fewer annual deaths related to smoke.^[1] Smokeless fuels serve as a potential replacement for fuels such as coal, which produce smoke upon combustion. Examples of smokeless fuels are anthracite, coke, charcoal and hexamine fuel tablets. Smoke-free carbonaceous fuels for domestic use are usually supplied in the form of standard pillow-shaped briquettes.
