Circulation ratio in boiler
WebJan 29, 2024 · Forced circulation is a type of circulation that is mostly present in boilers and evaporators. This process is employed in areas where scaling, thermal degradation and other negative impacts may occur. In the process, liquids are circulated at very high rates across the heat exchanger, preventing boiling. WebCirculation refers here to the flow of water, steam, or their mixture around the steam—water circuit in a boiler. In early days of boilers, steam was generated in a large vessel. The vessel was heated from outside, which would create a convective current within the large body of water.

It is considered that, for a particular boiler design, lowermost circulation ratio determines the most efficient boiler operation.
Webratio is equal to the downcomer mass flow divided by the steam mass flow leaving the boiler. For most steam-generator designs (Recirculation Ratio) = (Circulation Ratio) – 1. Both terms are in general use although the recirculation ratio is most commonly used to compare to, for example, thermalhydraulic code predictions. See also Section 3.1.
