Abstract (en)

[origin: WO9808025A1] A steam desuperheater has a body (38) extending into a steam line (16) and is operated by a controlled variable water pressure source responding to the amount of superheat in the steam line. As the pressure of the supply line is increased above a predetermined level greater than the steam pressure in the steam line (16), a piston (50) moves up against a calibrated spring (61) to progressively uncover a plurality of spray openings (73, 76) so that increasing water pressure results in an increasingly greater amount of water sprayed into the steam line.
