Dynamic Shrink/Swell and Boiler Level Control – Control Guru

The tubes producing large quantities of steam are termed risers and those principally carrying water down to the mud drum from the steam drum are termed downcomers. Excluding the tubes subject to radiant heat input from the firebox flame, a given tube will serve as a riser at some firing rates and a downcomer at other firing rates. The mechanics of the natural convection circulation of boiler water within the steam generator is the origin of the dynamic shrink/swell phenomenon.

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

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).
