The invention relates to a Yankee
drying hood arrangement (1) which is shaped to be fitted over a Yankee
drying cylinder (2) such that the
drying hood arrangement (1) can cover a part (4) of the circular cylindrical surface (3) of a Yankee drying cylinder (2). The Yankee drying hood arrangement (1) comprises a plurality of
nozzle boxes (5) distributed equidistantly around an imaginary axis (X) such that, when the Yankee drying hood arrangement (1) is fitted over a Yankee drying cylinder (2), the
nozzle boxes (5) are spaced from the circular cylindrical surface (3) of the Yankee drying cylinder (2) but form a curved structure (6) that follows the outer contour of the circular cylindrical surface (3) of the Yankee drying cylinder (2). Each
nozzle box (5) has a longitudinal extension in a direction parallel to the axial extension of the Yankee drying cylinder (2) and each nozzle box (5) has openings (7) distributed along the longitudinal extension of the nozzle box (5) through which openings (7) a fluid such as hot air can exit the nozzle boxes (5) and
stream towards the circular cylindrical surface (3) of the Yankee drying cylinder (2) at different points at different points along the axial extension of the Yankee drying cylinder (2). The Yankee drying arrangement further comprises a plurality of
distributor conduits (8) for a fluid such as hot air and the
distributor conduits (8) extend in the circumferential direction around the curved structure (6) formed by the nozzle boxes (5). Each
distributor conduit (8) is in communication with several nozzle boxes (5) such that a fluid such as hot air can
stream from each distributor conduit (8) to several different nozzle boxes (5). At least one main supply conduit (9, 10) for a fluid such as hot air is in communication with the distributor conduits (8) such that a fluid such as hot air can
stream to the distributor conduits (8). The distributor conduits (8) are oriented around the curved structure (6) of the nozzle boxes (5) in such a pattern that, when one and the same distributor conduit (8) communicates with different nozzle boxes (5), it does so at different points along the longitudinal extension of the different nozzle boxes (5). The invention also relates to a Yankee drying cylinder fitted with the inventive Yankee drying hood arrangement and to a method of drying a fibrous web.
