| Summary: | The design of a shell and tube heat exchanger (STHE) plays a crucial role in various industrial applications, particularly in steam generation processes. This study focuses on the engineering and thermal analysis of shell and tube heat exchangers, which are widely used for their high efficiency, robustness, and versatility in handling different fluids. The analysis begins with an overview of various steam generators, including fire-tube, water-tube, nuclear steam reactors, and once-through boilers, highlighting their operational principles and applications. In fire-tube steam generators, hot gases produced from combustion pass through tubes submerged in water, where heat transfer occurs. Conversely, water-tube boilers circulate water within tubes heated by external flames, allowing for higher pressure and temperature operation. The once-through boiler represents an advanced design where water flows continuously through the heat exchanger, producing steam without the need for a steam drum. Each type of steam generator presents unique challenges and advantages, influencing the selection of an appropriate heat exchanger design. The design analysis of the STHE emphasizes critical parameters such as flow arrangement, surface area, and material selection. Additionally, the integration of design considerations for engineering detailing as well as simulation using ANSYS software and modeling using Solidworks.
The findings underscore the significance of tailoring the STHE design to specific steam generation needs, considering factors like fluid properties, thermal load, and operational constraints. This study contributes to the ongoing development of efficient thermal systems and emphasizes the importance of innovative heat exchanger designs in enhancing steam generation efficiency across various industrial sectors. |
