The water spray design of the Pick Heaters “Series DS” Desuperheater offers a simple, cost effective method of cooling steam to within 10°F of saturation.
The desuperheater is a water spray type with single nozzle. This design has limited turndown and is intended for applications having relatively constant steam flow and cooling water demand.
The spray nozzle is located in the center of the housing, providing axial injection in the direction of steam flow. A thermal sleeve isolates the main housing from contact with cooling water to prevent thermal stress and conical insert accelerates steam to promote turbulence and rapid absorption of cooling water.
The Pick Desuperheater is designed and fabricated to meet customer specified diameter, material, flange rating, and MAWP.
