In a vertical sectional boiler, the sections are placed?

In a vertical sectional boiler, the sections are indeed placed one above the other. This design allows for a compact configuration that efficiently utilizes vertical space. Each section of the boiler is designed to contribute to the overall heating surface, which is essential for the boiler's ability to generate steam or hot water.

The vertical arrangement helps facilitate the natural rise of steam and the circulation of water, leading to effective thermodynamic processes within the boiler. This configuration is advantageous for maintenance as well, since individual sections can often be serviced or replaced without requiring substantial disassembly of the entire unit.

Understanding this structural layout is crucial for anyone studying power engineering, as it influences both the performance and the efficiency of the boiler system. In this case, the choice that suggests the sections are placed side by side does not accurately represent the design of vertical sectional boilers.
