Which is a characteristic of a sectional boiler?

A sectional boiler is characterized by its construction method, which involves multiple vertical sections that are clamped together. This design allows for easier deployment and has the flexibility that makes it suitable for various applications. The clamped sections create a more efficient heat transfer surface than a traditional single-unit boiler, enhancing performance.

In addition, because these boilers are built in sections, they have the advantage of being transported and assembled on-site, which is an important feature in environments where space might be tight or accessibility is an issue. The ability to add or remove sections as needed also allows for system modifications over time, contrary to the belief that they cannot be modified once built. Understanding this is crucial for anyone working with or evaluating boiler systems, as it impacts installation and maintenance considerations.
