    Water is introduced into the steam drum and is circulated around the boiler, leaving only as steam. What makes the forced circulation boiler different is its use of a secondary pump that circulates water through the boiler. The secondary pump takes the feed water going to the boiler and raises the pressure of the water going in. In a natural

  • Natural Circulation in Boilers - venus-boiler.com

    ANALYZING FOR BOILER WATER CIRCULATION In a circuit, the circulation takes place due to difference in density between the cold water in the downcomer circuit and the density of steam water mixture in the evaporator tube. The flow will increase as the heat input is more and the density of water steam mixture decreases in the evaporative circuit.

    Jun 01, 1945 · A thermodynamic evaluation is made of the work available for, and the resistance to circulation by, natural convection in a water-tube boiler. This leads to a theory of circulation which is independent of the usual type of hydraulic theory expressed in terms of density difference. The theoretical circulation equation is first used for the direct estimation of examples of particular circuits.

    Up to10%cash back · Circulation 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. This process did not pose any threat to the safety of the boiler.
