Desuperheaters for Waste-to-Energy Plants

B-Tech Valve offers fixed-nozzle spray-ring designs, including the SPAD Small Pipe Attemperator Desuperheater and Steam Attemperator, as well as the variable-nozzle probe-type LPD Large Pipe Desuperheater. Replacement Parts for Desuperheater Valves are also available for component-level maintenance and repair requirements.

The listed desuperheater products are available across ASME B16.34 pressure classes from 150 through 2700. The specific pressure class should be selected against the steam system design conditions, piping requirements, and applicable plant engineering specifications. B-Tech Valve can provide application guidance for the required configuration.

The listed products are rated for temperatures up to 1200°F (650°C). Actual selection should consider the operating temperature, steam conditions, water injection arrangement, piping configuration, and control requirements of the waste-to-energy plant.

The SPAD uses a fixed-nozzle spray-ring design and clamps between two steam pipe flanges. It receives feed water from a separate temperature control valve. This arrangement is intended for smaller steam piping and should be reviewed against the plant's line size and installation requirements.

The LPD uses a probe-type variable-nozzle, fully actuated control valve and desuperheater assembly. It is inserted at 90° through a flange on the steam pipe and is intended for pipe sizes 6 inches and larger. Application sizing and system conditions should be confirmed before selection.

Replacement Parts for Desuperheater Valves are offered as American-made components for component-level installation. The parts are compatible with ASME B16.34 pressure classes 150 through 2700 and are temperature rated to 1200°F (650°C). They support steam flow optimisation, equipment protection, and maintenance of power and process plant steam systems.
