What is good to know about the manufacture of wood briquettes for heating before buying them

Wood briquettes are a standardized organic fuel, which has a high calorific value of 17.5 to 19.5 MJ /kg (35 to 45% higher heating value than one year air dry firewood – about 30% humidity). Manufacture of wood briquettes is the spitting image of the manufacture of wood What is good to know about the manufacture of wood briquettes for heating before buying them pellets, the only difference is that briquettes are larger. The most commonly have a diameter from 20 to 120 mm and a length of 400 mm. Wood briquettes for fuel is made ​​from shavings, sawdust and dry wood dust. To increase the strength  can be added 1-3% organic additives in the form of corn flour or potato starch. Input material for briquettes must have humidity less than 15%. The material is pressed under a pressure of 5000 kg/cm2. For drying dryers are used What is good to know about the manufacture of wood briquettes for heating before buying them dryers which work at the entrance at 110 °C and at the exit at 70 °C.

Standardized wood briquettes for heating in Europe must not contain recycled wood or outside contaminants. Recycled materials such as treated or painted wood panels are useless for the production of wood briquettes. The combustion could lead to release of harmful emissions and/or to uncontrolled changes in heating properties of wood briquettes.
