<p>The invention relates to a plant for heat recovery from the warm and the humid air resulting from the paper drying process. According to the invention, the plant uses, in a paper dehumidifier (1), air recirculated by using a piping (2) of a heat exchanger (3) and of a fan (5) wherefrom, by indirect water cooling, a part of the water vapours are condensed, the latent heat being absorbed by the cooling water through the secondary steam resulting from the cooling water evaporation in a cooler (7), said steam being absorbed by the live steam jet supplied through a pipe (10), there resulting average parameter steam, which is distributed through some pipes (11 and 12) to the consumers, the cooling water being recirculated in closed circuit through a pipe (6) of the cooler (7) and of a pump (8).</p> |
