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 modified from the Xfh training workshop. We discuss the following values,...

Beyond the Basics: Understanding the Xist Vibration Report
January 15, 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...

TechTip: Tube Spans in the Xist Vibration Report
January 16, 2017
Xist automatically generates a vibration analysis report for all cases. The software selects tube spans for analysis based on a range of factors, including TEMA shell type, baffle type and baffle orientation. While users are generally familiar with the structure of the vibration report for TEMA E shells, the methods applied...

F-24 Demonstration of RFU as Research Tool
March 27, 2017
In 2013 HTRI commissioned the Rotating Fouling Unit (RFU). With its smaller volume, shorter run duration, and faster turnaround, the RFU serves as a screening device for the High Temperature Fouling Units (HTFU-1 and HTFU-2) and is ideal for fouling impact studies on specific variables. Initial fouling tests and fouling impact...
