Zusammenfassung:The invention relates to ecological briquettes used as fuel and to a process for preparing the same. The claimed briquettes comprise chips of comminuted reed material, free of adhesive or other chemical additives, with a diameter of 60 mm and lengths of 20...80 mm. The claimed process consists in comminuting the reed stalks with inflorescence up to a length of 3...30 mm and a thickness of 0.2...0.6 mm, pressing the comminuted material into cylindrically-shaped briquettes with an average density of 880 kg/m, the resistance to statical compression perpendicular to the external circumference of 2...4 N/mm, calorific power of 20 000 kcal/kg. Invenţia se referă la brichete ecologice, utilizate drept combustibil şi la un procedeu de obţinere a acestora. Brichetele conform invenţiei sunt constituite din aşchii de material mărunţit din stuf, fără adeziv sau alţi aditivi chimici, cu un diametru de 60 mm şi lungimi de 20...80 mm. Procedeul conform invenţiei constă din mărunţirea tulpinilor de stuf cu inflorescenţă până la lungimi de 3...30 mm şi grosimea de 0,2...0,6 mm, presarea materialului tocat, rezultând forme cilindrice cu o densitate medie de 880 kg/mc, rezistenţă la compresie statică, perpendiculară pe circumferinţa exterioară, de 2...4 N/mmşi putere calorifică de 20 000 kcal/kg.
