  • difference between subcritical and supercritical boiler

    Difference Between Subcritical and Supercritical Boiler

    The heated fluid is used in various applications including water heating, central heating, cooking, etc. Subcritical and supercritical boilers are such steam generating systems. The key difference between a Subcritical and supercritical boiler is that Subcritical boilers work at a subcritical pressure of the fluid whereas supercritical boilers work at a supercritical pressure of the fluid.
