Carraro - Desuperheater VariBull
Variable injection area
The variable injection area provides a perfect atomization of the water by means of the nozzles. These nozzles are mounted in a pipe piece (chamber) which is controlled by a control valve mounted before the Desuperheater.
The required number of nozzles is connected via a bracket welded to the tube (chamber). This tube (chamber) comes with BW ends and is therefore welded into the steam line. The water connection is in flange design (ANSI, UNI or DIN).
The tube (chamber) can be lined inside with a liner. It is recommended to install a filter (strainer) before the water connection.
