Steam Desuperheaters

Desuperheating, sometimes called attemperation or steam conditioning, is the reduction of gas temperature. It's most common application is the reduction of temperature in a steam line through the direct contact and evaporation of water. Our desuperheaters use uniquely effective methods to inject the water and maximize the surface contact area between the steam and water to increase the rate of water evaporation. Most of our desuperheaters inject water through several small holes into the path of the high velocity steam where the water is atomized into small water droplets and quickly evaporated into the steam. Thermal pipe liners are not normally required.

Desuperheaters are used in power boiler heat recovery systems, for superheater interstage temperature control, paper dryer drum temperature control, steam kettle or cooker temperature control, and aircraft catapult machines.

Most desuperheaters can be installed horizontally or vertically. Desuperheaters are often supplied with steam and water control valves and controllers to provide an automatically controlled system. The controllers can be either pneumatic or electronic.
