Two-stage Dump Tube

Low-noise dump to condenser solution

The dump tube is used together with a steam conditioning valve in applications such as turbine bypass where steam is dumped into a condenser. The process can, in case of high pressure drops between the steam conditioning valve outlet and the condenser, be a source of high levels of noise. In order to remedy this, IMI CCI has developed a multi-stage dump tube which splits the pressure drop over a series of pressure reducing stages, thus reducing the noise level. IMI CCI has experts in the field of dump tubes, with experience from thousands of plants, that can provide support at the design stage.

 

  • The dump tube is welded to the steam pipe downstream of the bypass valve.
  • The dump tube is a fixed orifice, which reduces the bypass steam pressure down to the pressure of the condenser.
  • Our dump tubes are carefully calculated to allow it to be used as a flow meter.
  • There are two main applications for the dump tube: – Water cooled condenser, where the dump tube is mounted in the condenser- Air cooled condenser, where the dump tube is mounted in the bypass line connected to a header going from the turbine outlet to the air-cooled condenser.
