A briquette (or briquet) is a compressed block of coal dust[ or other combustible biomass material such as charcoal, sawdust, wood chips,[2 peat, or paper used for fuel and kindling to start a fire. The term derives from the French word brique meaning brick. (wikipedia source)
Coal briquettes have long been produced as a means of using up ‘small coal’, the finely broken coal inevitably produced during the mining process. Otherwise this is difficult to burn as it is both hard to arrange adequate airflow through a fire of these small pieces, also it tended to be drawn up and out of the chimney by the draught, giving visible black smoke.
The first briquettes were known as culm and were hand-moulded with a little wet clay as a binder. These could be difficult to burn efficiently, as the unburned clay produced a large ash content, blocking airflow through a grate.
Now producing of briquettes using modern maching with the processing started from screening the raw material, crushing raw material, mixing raw material with water and tapioca binder (natural binder), first blending and second blending, pressing as block other form, cutting and drying process by sun or oven room.
Briquettes is used for BBQ or Shisha/hookah, boiled machine, heater room, and many usage of briquettes
