<p>A desuperheater apparatus (1) for steam lines, which comprises a plurality of chambers (2, 3, 4) including a final chamber (4) whose upstream end is closed by a steam diffuser (11) having a plurality of holes (12) for the passage of steam. Spray nozzles (9) are associated to the final chamber (4) for generating respective spray cones therein. Advantageously, the steam diffuser (11) has a conical shape so that, at each spray nozzle (9), the perforated portions of the steam diffuser (11) are inclined in such a manner as to be substantially parallel to the lateral surface of the spray cones (C) generated by their corresponding spray nozzles.</p> |
