Blakeborough®

BV986 Desuperheater

The Blakeborough® BV986 desuperheater is designed as a compact solution suitable for steam conditioning applications for pipe sizes up to 6 inches.

This BV986 unit offers a relatively simple and inexpensive solution for applications which have low rangeability and stable steam demand.

The unit is a simplified spray nozzle where the spray water is circulated around an internal gallery and then injected into the steam through a series of radial holes.

The Blakeborough® BV986 unit also fits between conventional flanges and is therefore easy to remove for service and maintenance purposes. The unit is connected to a stand-alone spray water valve which controls the amount of water being injected into the vapor. The BV986 can also be directly mounted onto the outlet of a pressure control valve so that water is injected into the turbulent vapor flow at the outlet of the valve. The BV986 desuperheater is used on pipe sizes from 25mm (1 inch) and above.
