Beyond the Basics: Understanding the Xist Vibration Report
January 16, 2017
Avoiding flow-induced vibration problems in shell-and-tube exchangers is an important task best accomplished at the design stage. Xist® completes a screening analysis using mechanistic-based methods that have been validated with real cases and data. Because there are two types of vibration (tube and acoustic) and several excitation mechanisms, careful examination of...

Beyond the Basics: Interpreting Xfh Output
January 16, 2017
Xfh® has a total of 37 output reports, and today we will look at key numbers on six of these reports (output summary, cylindrical energy balance, stack monitor, convection summary, cylindrical firebox monitor, and combustion streams) using an example. We discuss the following values, which can be located in these reports:...
