Get a QuoteHow do supercritical steam conditions affect plant design and cost? Once-through boilers used in supercritical plants have a number of differences from the drum-type boiler typically used in subcritical plants. In a once-through design, water is completely evaporated in a single pass through the boiler rather than re-circulating through the drum.

Drum type boilers operate only at sub-critical steam pressures and the pressure of the boiler is based on the firing rate and steam flow. In a subcritical unit, it is easy to separate water from steam. Above the supercritical pressure, steam and water cannot be separated.
