Abstract
A steam desuperheater has a body extending into a steam line 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, a piston moves up against a calibrated spring to progressively uncover a plurality of spray openings so that increasing water pressure results in an increasingly greater amount of water sprayed into the steam line.
