Abstract (en)

[origin: WO2010091765A1] The invention relates to a method for recapturing steam when drying a tissue paper web having a cylinder (10) fed from a fresh steam network (1) and a hot air hood (11) blowing hot air onto the tissue paper web, comprising the steps of: removing condensate from the cylinder; compressing the condensate to a first pressure level substantially corresponding to that of the fresh steam network; heating the condensate by heat exchange with the exhaust air from the hot air hood; vaporizing the condensate; and feeding the generated steam into the fresh steam network.
