I am selling fuel pellets(granules) from husks
sunflower. Their calorific value is 19800-21000 kJ/kg, which is more than that of wood and comparable to some
types of coal. When burning 2,000 kg of fuel pellets, the same amount of thermal energy is released as when burning 3,200 kg of wood, 957 cubic meters of gas, 1,000 liters of diesel fuel or 1,370 liters of fuel oil.
