Abstract

The present invention deals with a method and an arrangement for heating of pulp, in which method low- pressure steam is supplied to the pulp so that the pulp is subjected to pressure prior to the introduction of the low-pressure steam in its direction of flow, such that the pressure on the pulp at the steam introduction point is lower than the pressure on the available steam, and after the steam introduction the pulp is stirred in order to either distribute the steam evenly in the pulp and/or to equalise the temperature of the pulp. <IMAGE>
