Abstract

METHOD FOR CONTACT-FREE DRYING OF A PAPER OR BOARD WEB A method for contact-free drying of a paper or board web (W). In the method both infrared radiation and drying air jets are used for drying, the web (W) moving through the dryer (10, 20) being, at the same time, supported free of contact with the dryer by means of the drying air jets. In the method the web (W) is first passed into an infrared drying gap or gaps (10VA, 10VB) and thereupon into an airborne web drying gap (20V). In the method the infrared radiators 105 in the infrared drying unit or units (10A, 10B) are cooled by means of air flows (FAin, FBin). In the method, before the airborne web dryer (20), an infrared dryer unit or units (10A, 10B) is/are used that are closed in such a way that cooling air is not, at least not to a substantial extent, passed into the infrared drying gap (10VA, 10VB). The drying cooling air which has been heated in the closed air circulation in the infrared drying unit or units (10A, 10B) is conducted through the nozzles (251, 252) of the airborne web dryer (20) following after the infrared dryer to constitute drying and supporting air blowings in the drying gap (20V) in the airborne web dryer, The thermal energy (Q) recovered in the cooling air of the infrared dryer (10) is substantially completely conducted to the airborne web dryer (20) to constitute heating energy at the side (302) of the airborne web dryer (20) which side (302) is placed at the dry side opposite to the coated wet side (P) of the web (W) to be dried.
