Abstract: While using the waste of agricultural plants for fuel, an issue of its preparation for burning arises. Much work in this field is done in Germany, England, Denmark, Hungary and Poland. In Germany 20 % of all amount of grown straw is used for energy production which equals to 1.5 million tons of oil products [1,2]. The energy value of briquettes straw ranges from 12 to 14.3 MJ/kg. Therefore, while using straw briquette for fuel we would get only slightly smaller amount of energy compared with firewood, the energy value of which is 15.5 MJ/kg [3–5]. In many cases wood sawdust is pressed. At present most often 50–60 mm diameter briquettes, the length of which is 5–20 cm [3], or square ones are produced. Pelleted fuel is common in the Western European countries. Though special equipment is needed for heating and production cost is much higher, pellets are widely used, especially in Denmark and Sweden. The work objective and tasks are to establish the optimum length of straw chaff, its moisture and pressure force for producing straw briquettes intended for burning in heating boilers and to evaluate their density variation during storage
