Multi-Nozzle Desuperheaters for High Turndown

These desuperheaters are used in power plants and process plants where steam must be conditioned for equipment protection, heat transfer or flow management. Listed applications include protecting piping and steam traps, protecting rotating seals, increasing steam flow, decreasing boiler loads and reducing fuel costs. Final selection should reflect the steam line and operating application.

The spray-ring design clamps between two steam pipe flanges, providing a component-level installation arrangement within the steam line. Feed water is supplied from a separate temperature control valve. Connection details, pressure class and application sizing should be reviewed against the existing piping arrangement before specifying a unit.

The listed products are available in ASME B16.34 pressure classes ranging from 150 through 2700, with specific classes including 150, 300, 600, 900, 1500, 2500 and 2700. The appropriate class depends on the steam system and installation requirements. B-Tech Valve can provide application guidance for selecting a suitable configuration.

The desuperheater products are rated for temperatures up to 1,200°F (650°C), according to the supplied product information. Operating conditions, water injection control and pressure class should be evaluated together when selecting equipment. Confirm the required application conditions with B-Tech Valve before final specification.

B-Tech Valve offers Replacement Parts for Desuperheater Valves, including American-made components compatible with ASME B16.34 pressure classes 150 through 2700. The parts are described as stocked in-house for quick turnaround availability and can support steam trap protection, rotating seal protection and steam flow optimisation in plant systems.

Sizing considers the steam system, pipe arrangement, required temperature conditioning and operating conditions. The Steam Attemperator is described as sized for each customer's application, while the SPAD design is intended for small steam piping. B-Tech Valve's application engineering contact can review the system information needed to identify an appropriate product configuration.
