FIELD: process engineering.
SUBSTANCE: invention relates to thermal processing of timber and may be used in woodwork, furniture production, etc. Proposed method comprises gradual heating to 200…240°C and keeping timber at said temperature for 5…7 h. Heating and curing at preset temperature are carried out in atmosphere of flue gases resulted from woodwork wastes gasification and synthesis gas combustion with surplus air factor of 0.95 to 1.0. Flue gases are cooled down in heat exchanger to 200…240°C. Excess heat power picked up in said cooling is directed for timber preheating.
EFFECT: power savings.
