HEAT EXCHANGER DEVICE OPERATING METHOD AND HEAT EXCHANGER DEVICE

摘要

The heat exchanger device operating method can prevent the adherence of a scale to a heated liquid flow path, while keeping the amount of heat transferred to the heated liquid constant. With the heat exchanger device operating method, after the heated liquid is heated by heat exchange with a thermal medium and flows out the heated liquid flow path, part of the heated liquid flows into a heated liquid circulation pipeline, pulsations are produced in the inflowing part of the heated liquid by the intermittent driving of a circulation pump, and the heated liquid in which pulsations have been produced again flows unchanged into the heated liquid flow path.
