method for heating and kuehlen of pulpen and waermeaustauscher velvet plant for the application of the procedure.

摘要

The method of the invention is especially suitable for heating cellulose pulp suspensions of consistencies up to nearly 20 per cent of the paper industry or for heat recovery therefrom. At least one end (2) in the side of the pulp inlet opening (5) of the heat exchanger (1) is provided with a device (7), a so-called fluidizator, to loosen bonds between fibres of the pulp suspension, which fluidizator changes the pulp suspension to a fluid form and effects its uniform distribution to the heat exchange channels (8).
