ABSTRACT:
Distillate produced by the condensing stage of an evaporation installation is conducted to a reservoir to be preheated to its boiling point in preparation for a further degassing step. The required rise in temperature of the distillate in the reservoir is effected by the heat of condensation of a portion of the steam directed via a main pipe from the evaporating stage of the installation to the condensing stage. The required contacting of such steam portion with the reservoir is effected by diverting, to the reservoir, a portion of the steam in the main pipe via a diaphragm or another blocking member interposed in the main pipe and a branch pipe that communicates with the main pipe upstream of the diaphragm member and extends to the reservoir. A conventional overflow pipe disposed at a predetermined height in the reservoir is effective to conduct the heated distillate to the subsequent degassing stage.
