A YANKEE DRYING HOOD ARRANGEMENT, A YANKEE DRYING CYLINDER FITTED WITH A YANKEE DRYING HOOD ARRANGEMENT AND A METHOD OF DRYING A FIBROUS WEB

The invention relates to a Yankee drying hood arrangement (1) which has a first temperature main supply conduit (9, 9′) for a fluid such as hot air, or hot air and steam and/or water vapour, at a first temperature T1 and a second temperature main supply conduits (10, 10′) for a fluid such as hot air, or hot air and steam and/or water vapour, at a second temperature T2 which is not the same as T1, the first temperature and second temperature main supply conduits (9, 9′, 10, 10′) being in communication with the distributor conduits (8) such that a fluid such as hot air can stream from the first temperature and second temperature main supply conduits (9, 9′, 10, 10′) to the distributor conduits (8), wherein at least one distributor conduit (8) is provided with damper means (31) for changing the ratio between amount of fluid at temperature T1 from the first temperature main conduit and the amount of fluid at temperature T2 from the second temperature main conduit that streams into the distributor conduit.
