FIELD: drying solid materials.
SUBSTANCE: method comprises maintaining concentration of flue gas in the drying chamber at a level of 60-95 volume per cents by maintaining the pressure of gas inside the drying chamber in the range from 1.5 to 5 atm. The wood fuel, e.g. wood waste, is set in the combustion chamber provided in the bottom section of the furnace for generating flue gas, the fuel is burnt out, and high-temperature flue gas is supplied to the top section of the drying chamber which received damp wood thus providing the heat drying of wood by flue gas.
EFFECT: enhanced efficiency of drying.
