Qu'est-ce qu'une briquette?

Une briquette est un morceau de matériau combustible qui est couramment utilisé pour allumer et maintenir un incendie, soit dans une chaudière, un gril ou dans un espace ouvert comme un foyer. It is commonly in the shape of a square or rectangle, but can also be found in lump form or other molded shapes. The size of the briquette is dictated by how it will be used. Les briquettes plus grandes sont souvent utilisées dans un environnement de fabrication et les versions plus petites sont principalement utilisées dans les cheminées et à des fins de grillades en plein air. The most popular briquettes are biomass and charcoal varieties.

The majority of biomass briquettes are made from sawdust or similar wood waste products. Le processus de fabrication consiste généralement à compresser la sciure de bois et à le forcer dans une machine qui la chauffe et extrude les briquettes en forme de petits journaux de cheminée. Les particules dans le journal sont maintenues ensemble par une substance naturelle dans la sciure, donc aucun liant n'est nécessaire.

Charcoal briquettes are commonly used to cook food on outdoor grills, barbecue pits and hibachis. The lump form, typically made from hardwood materials, is favored by some cooks. This preference is generally attributed to the fact that lump charcoal produces considerably less ash than charcoal briquettes.

Starch is commonly used as a binder for charcoal briquettes. Igniting aids are frequently added to some briquettes and generally include paraffin, petroleum solvents, borax and sodium nitrate.
