Fixed area nozzle(s)

DV1 Venturi

Description

Simple construction

  • Fixed-area spray nozzle
  • For small line size with an upstream steam pressure- reducing valve (PRV)
  • Relies on the energy of steam ow for atomization

Typical applications

  • Process steam desuperheater downstream of existing steam PRV
  • Small PRDS
