Abstract
A falling film evaporator includes a shell with a number of heat transfer elements within the shell. Each heat transfer element has two opposed essentially rectangular plates joined together along upright sides and along seams substantially parallel to the upright sides. The seams form with each other, and the upright sides, a number of vertical flow channels through which steam (heating fluid) flows in the interior of the heat transfer elements to evaporate evaporable liquid flowing downwardly in a film over the outer surfaces of the heat transfer plates.
