Investigation of Heat Transfer during Boiling of Spent Alkaline Solutions in Evaporator Tubes

摘要

The results from investigating the heat transfer during boiling of aqueous foam-forming solutions in a vertical tube are presented; it is shown that the heat transfer occurring under these conditions is determined by the combined effect of operating parameters, which manifests itself through the mechanism for the formation and redistribution over the tube height of zones with typical regimes. Equations for calculating the heat-transfer coefficient in the vertical tube are given.
