Heating steam or cooling water is passed inside the heat tube and outside the heat transfer tube to perform mutual heat exchange. However, since impermeable graphite material is weaker than metal-based materials, it is necessary to make the tube sheet that fixes the heat transfer tube bundle large and heavy, which has the drawback of making it extremely difficult to handle and assemble. be.
