Desuperheaters for District Energy and Campus Plants

B-Tech Valve offers fixed-nozzle spray-ring designs and a probe-type variable-nozzle design. The SPAD and Steam Attemperator use a spray ring and clamp between steam pipe flanges, while the LPD uses a fully actuated variable-nozzle control valve with flanged insertion at 90 degrees on the steam pipe.

The product range includes SPAD Small Pipe Attemperator Desuperheater equipment for steam pipes 4 inches and smaller, according to the company information. The LPD Large Pipe Desuperheater is intended for pipes 6 inches and larger. The Steam Attemperator is sized for each customer's application.

The listed desuperheater products are available in ASME B16.34 pressure classes ranging from 150 through 2700. The applicable class should be selected against the plant's steam conditions, piping design and installation requirements. B-Tech Valve can use the application details to help identify a suitable configuration.

The listed products are rated for temperatures up to 1,200°F (650°C). Actual selection should consider the steam system's operating conditions, water injection requirements, pipe arrangement and downstream equipment protection objectives. Product documentation and application review help confirm suitability for a specific campus or district energy installation.

A spray-ring desuperheater uses fixed nozzles to introduce water into the steam pipe. The SPAD and Steam Attemperator receive feed water from a separate temperature control valve and clamp between two steam pipe flanges. This arrangement supports steam conditioning while helping protect piping, steam traps and rotating seals.

B-Tech Valve offers Replacement Parts for Desuperheater Valves, including American-made components compatible with ASME B16.34 pressure classes 150 through 2700 and temperatures up to 1,200°F (650°C). The parts support steam flow optimisation, steam trap and rotating seal protection, and reduced boiler loads in plant steam systems.
