Q3) (a)

Explain the construction and function of Steam separator with neat sketch. Also mention its specific location in the system.

Function

  • It separates water particles from steam before it is supplied to a steam engine or turbine. Thus it prevents the damaging of turbine blades due to moisture present in steam.

Location

  • It is located in the supply line near the turbine or engine.

Construction

  • The separator with baffle plates is shown in figure.
  • It consists of a cylindrical vessel. The vessel is fitted with baffle plates.
  • A water gauge is fitted to indicate the water collected in the separator to drain away to separated water.

Working

  • The steam is allowed into the separator. The steam strikes the baffle plates and the direction of the flow is changed.
  • As a result, heavier water particles in steam falls down to the bottom of the separator. The separated steam is free from water particles.
  • It is then passed to the turbine or engine through the outlet pipe.
