Modeling kettle vaporizers presents multiple challenges, including entrainment and circulation issues. As part of the kettle Circulation Boiling Model (CBM), Xist modifies the heat release curve (program calculated or user specified) to create a unique kettle three-point heat release curve to determine the temperature profile within the bundle. This webinar focuses on when and how approximations in Xist’s modified kettle heat release curve may affect kettle vaporizer cases. It also presents an alternative modeling technique to better evaluate the bundle conditions for cases that require a more accurate heat release curve.
