Milled woodwork refuse, compressed into cylindrical granules. Usually 10-30 mm in length and 6-10 mm in diameter. Pellets are shaped under the pressure of about 300 atmospheres. As with briquettes, they hold their shape by means of natural polymeric compounds. The heat capacity value of the pellets is approximately 4300 kcal/h. A ton of wood pellets in combustion produces approximately as much heat as 480 m3 of gas, 500 liters of diesel fuel or 700 liters of masout. Whereby, pellets are an undoubtedly more environmentally friendly type of foul, as due to their low wetness they release less carbon dioxide, leave a smaller amount of ash, and there is next to no sulfur contained in their emissions .
