### Q: What is the primary function of a reboiler in industrial processes?
**A**: A reboiler provides the necessary heat to vaporize a portion of the liquid from the bottom of a distillation column or other separation process, enabling continuous operation and efficient separation of components.

### Q: What materials are commonly used for reboiler construction and why?
**A**: Reboilers are typically constructed from carbon steel for cost-effective general applications or stainless steel for corrosive environments. Both materials offer durability and efficient heat transfer properties suitable for industrial machinery manufacturing.

### Q: How does the tube bundle affect reboiler performance?
**A**: The tube bundle is a critical BOM component that determines heat transfer efficiency. Proper tube bundle design maximizes surface area for heat exchange, ensuring optimal vaporization rates and energy efficiency in distillation and separation processes.
