<p>PROBLEM TO BE SOLVED: To provide an evaporation can device capable of individually stopping heating by a plurality of condensation surfaces, while restraining a cost increase.SOLUTION: The evaporation can device 100 comprises auxiliary partition plates 4a-4c formed in a concentric ring shape so as to project in the bottom part inner surface direction of a heating vessel 2 from a bottom part outer surface of an evaporation can 1 and partition plates 3a-3c formed in a concentric ring shape via clearances 9a-9c in the radial direction of the auxiliary partition plates 4a-4c so as to project in the bottom part outer surface direction of the evaporation can 1 from a bottom part inner surface of the heating vessel 2, and comprises a partition wall group for partitioning passages 8a-8c mutually communicating via the clearances 9a-9c in a vapor passage 8, drain pipes 11a-11d for draining a condensate generated by condensing by the passages 8a-8c and a plurality of flow regulating valves 12a-12d for sealing the clearances 9a-9c by the condensate by adjusting a discharge amount of the condensate drained from the respective drain pipes 11a-11d.</p> |
