function of steam drum cyclone separator

The Boiler Circulatory System: Beyond

May 01, 2011Cyclone separators spin the wet water/steam mix in a cyclonic action, separating the water out of the wet mixture by centrifugal force. The wet moisture falls down into the lower half of the steam drum, where it is mixed with the water/steam coming from economizer outlet header, goes into the downcomers, and begins the circulatory process all over again.

What is the purpose of the steam drum on a water tube

The steam drum is primary used on water tube boilers and HRSGs. It contains internals such as the agglomerators and the cyclone separators, chevrons, demister pads, and any combination thereof. The primary function of the steam drum is separate water from steam which prevents carryover of the condensate into to the steam header (phase separation).

Carryover and its Causes

Operating the boiler at pressures significantly lower than design pressures is a cause of carryover. Lower the steam pressure more will be the specific volume of the steam inside. Hence, the steam velocity in drum internals would be more at lower pressures. This will hamper the separation of water droplets from steam which results in carryover. 2.
