1. The main changes between GB/T151-2014 and GB151-1999 are the updates to the safety regulations, design parameters, and material selection, thereby making the standards more in line with current technical and safety requirements. 2. Heat exchanger simulation software typically includes functions such as input/output configuration, property data simulation, result adjustment, and export. To simulate the physical properties of new substances, it is necessary to add the relevant property parameters to the software and make adjustments to ensure the accuracy of the simulation results. Users can import property data generated by software such as ASPEN PLUS into HTRI and EDR software for further analysis. 3. When selecting the shell-and-tube structure and tube-side parameters, it is necessary to consider the TEMA and GB151 standards in order to choose appropriate end caps, shells, and heat exchange tubes. In addition, it is also necessary to set an appropriate tube layout, baffle type, and gap, etc. 4. The training includes software operation demonstrations and Q&A sessions to help participants become familiar with and master the software’s functions. 5. The practical application section covers the structural overview of air coolers and economizers, optimization directions and problem classification, and illustrates through examples how to conduct design verification and simulation. 6. Finally, the course also covers the design and simulation of plate heat exchangers, explaining plate selection, process setup, and optimization strategies, with detailed analyses through practical examples. .
