Some charcoal briquettes. A briquette (French:; also spelled briquet) is a compressed block of coal dust [1] or other combustible biomass material (e.g. charcoal, sawdust, wood chips, [2] peat, or paper) used for fuel and kindling to start a fire. The term is a diminutive derived from the French word brique, meaning brick.
The extrusion production technology of fuel briquettes is the process of extrusion screw wastes (straw, sunflower husks, buckwheat, etc.) or finely shredded wood waste (sawdust) under high pressure when heated from 160 to 350 °C.
Screw extrusion is used to compact biomass into loose, homogeneous briquettes that are substituted for coal in cofiring. This technology creates a toroidal , or doughnut-like, briquette. The hole in the center of the briquette allows for a larger surface area, creating a higher combustion rate.
The 2nd standard briquette is cylindrical in shape, weighs 3.5 kilograms (7.7 lb), and is about 20 cm (7.9 in) in height and 15 cm (5.9 in) in diameter. The standard briquette has 22 holes drilled into its top to facilitate steady, efficient burning, and a household typically uses one to three briquettes per day in the winter.
Charcoal Briquette A tubular type of wood briquette. Wood briquettes are a fuel source made out of dried, compacted wood. They are made from wood waste or byproducts and machine-compressed into a log or block shape, generally without added ingredients, [1] though they can have added materials like peat, bracken, or coffee.

Some charcoal briquettes of similar shape to coal briquettes. 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.
In Klein’s case, a Postal Service spokeswoman said, the problem is the road. Hillman Ridge is paved but narrows to a width slightly larger than a pickup truck as it approaches Klein’s property.
Briquettes may also include brown coal (heat source), mineral carbon (heat source), borax, sodium nitrate (ignition aid), limestone (ash-whitening agent), raw sawdust (ignition aid), and other additives. Sawdust briquette charcoal is made by compressing sawdust without binders or additives. It is the preferred charcoal in Taiwan, Korea, Greece ...
