Supercritical steam generators are frequently used for the production of electric power. They operate at supercritical pressure. In contrast to a "subcritical boiler", a supercritical steam generator operates at such a high pressure (over 3,200 psi or 22.06 MPa) that actual boiling ceases to occur, the boiler has no liquid water - steam separation.Get Price
The issues discussed above lead to supercritical boiler technology being given a reputation of having limited operating capability, complex maintenance issues, lower availability, and lower plant efficiency than expected. As a result, the trend in boiler type moved towards subcritical drum type boilers during the 1970s. 4.Get Price
