multiple-spray desuperheater
Blakeborough® BV985 WEIR Oil & Gas



  • Options:



OverviewThe standard model incorporates 12 carefully spaced spray nozzles designed for optimum dispersion in the steam flow, and to minimise coalescence of the droplets. Nozzles are arranged so that at low steam flows water is injected into high turbulence zone of the vortices shed from the desuperheater probe. The design incorporates swirl chambers and conical nozzle for optimum atomisation even at low superior pressures. Injection assemblies can be characterised to suit process requirements and nozzle selection can be changed after installation.Key features/benefits Variable Spray Nozzle – 12 spray nozzles spaced for optimum dispersion inthe steam flow; Large range of design Cv options; High rangeability Superior Pressure 1 bar to 50 bar (15psi to 740psi) Nozzle Rangeability – up to 40:1 Accurate control of steam temperatures without water droplet damage to pipe walls Swirl chambers and conical nozzles for optimum atomisation Simple low cost inline maintenance Interchangeable nozzles
