  • Advantages and New Technologies of High-AVT Water

    Water reaches this state at a pressure above 22.1 MPa (221 bar), also known as 'supercritical pressure' of water. Beyond this pressure, it is a homogeneous mixture of water and steam, as shown in Fig-1. Up to an operating pressure of around 19 MPa in the evaporator part of the boiler, there is a non-homogeneous mixture of water and steam in Learn More
