Desuperheaters

Transvac direct contact steam Desuperheaters (sometimes known as attemperators) are used as a method of steam temperature control, reducing the temperature of superheated steam.

A desuperheater’s function is to produce steam temperatures approaching saturation temperature (typically to within 3°C). To cool the superheated steam, a medium, usually water, is entrained and flashed into vapour by absorbing heat from the steam.
