Research Update: Modeling Flat Bundles in Kettle Reboilers
January 15, 2017
Engineers may design flat bundles in kettle reboilers by removing tuberows from round bundles to create a larger disengagement space. This webinar discusses application of the kettle reboiler circulation boiling model to flat bundles. It reviews calculations for the static driving head and maximum heat flux for flat bundles. We also...

BK1-15 Applications of Ideal Bundle Boiling Methods to X-shell and Kettle Reboilers
June 30, 2017
Flow boiling prediction methods were recently improved using data collected from ideal crossflow bundles. When applied with accurate property models, these modified methods also improve prediction of X‑shell and kettle reboiler heat transfer measurements. Future implementation of the modified methods in Xchanger Suite should improve the accuracy of flow boiling predictions;...

BK1-14 Heat Transfer of Kettle Reboiler Tubes Above the Liquid Level
January 16, 2017
This report reviews literature and HTRI kettle reboiler data obtained when the liquid level was below the top of the tube bundle. We propose both a method to predict the two-phase jet height above the liquid level and an algorithm for predicting the heat transfer coefficient above the liquid level....
