The extrusion production technology of 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 (320 to 662 °F).
Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only ...
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.
Some pure wood briquettes with the bark removed can have as low as an 0.3% ash content, while briquettes with added materials can have up to a 7% ash content. [2] Briquettes have a substantially higher energy content than logs per cubic foot due to their density, which means they take up less storage space and release more heat per lb. than logs.
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 ...
