Abstract
In a method for drying boards, which are guided in decks through a drying device, wherein the boards (8) in the drying device are brought into contact with drying air by means of an impinging jet ventilation and wherein the impinging jet ventilation is ensured by means of transversely ventilated nozzle boxes (7), the drying air is supplied by means of at least two fans (4a, 4b) arranged next to one another in an airflow of the drying air produced by a burner (1), which guides the drying air to the fans (4a, 4b).
Claims17
A method for drying boards, wherein the method comprises guiding the boards through a drying device, bringing the boards in the drying device into contact with drying air by an impinging jet ventilation, the impinging jet ventilation being ensured by transversely ventilated nozzle boxes, and the drying air being heated by a single burner in a ceiling unit arranged above the nozzle boxes and being supplied to at least two fans arranged next to one another in an air flow of the drying air and thereafter being passed to a pressure chamber which is located at a side of the nozzle boxes, the drying device comprising the ceiling unit in which the single burner heats the drying air, and the ceiling unit comprising the at least two fans arranged next to one another and in a way such that they can be supplied with the heated drying air from the single burner, and
- a ratio of an intake height of the at least two fans, in relation to an outer impeller diameter, being at least 0.5.
