Fisher™ TBX-T Desuperheater

The Fisher TBX-T desuperheater can be used in many applications to efficiently reduce the temperature of superheated steam to the desired set point. The TBX-T is available for installation in steam lines from DN 200 through DN 1200 (NPS 8 through 48) in diameter and are capable of maintaining steam temperatures to within 6°C (10°F) of saturation temperatures. Water atomization and vaporization are key elements in any steam conditioning application. The TBX-T design incorporates a spraywater manifold of variable geometry AF nozzles that produce a spray pattern over a wide operating range. These nozzles are strategically placed to achieve mixing and quick vaporization at all flowing conditions.

Key Features

  • CFD designed spray manifold determines water injection point and insertion depth for mixing and quick vaporization.
  • The TBX-T has the option of including an integral thermal liner inside the steam pipe. This construction is most commonly used in boiler interstage attemperation applications, where the desuperheater is exposed to high thermal cycling and stress, high steam velocities, and flow-induced vibration. The liner reduces the potential for thermal shock when cool water is introduced to the unit that is already heated to the operating steam temperature.
