A boiler is considered an industrial boiler when?

A boiler is categorized as an industrial boiler primarily when the steam it generates is utilized for a specific process. In many industrial applications, boilers provide steam for various purposes, such as driving turbines, heating materials, or facilitating chemical processes, which is a key characteristic distinguishing industrial boilers from other types.

This classification highlights the operational focus of the boiler: its design and functionality are intended to meet the demands of industrial processes rather than simply providing heat for comfort or space heating.

While continuous operation could be a characteristic of some industrial boilers, it is not a definitive criterion for classification. Similarly, the generation of steam for space heating aligns more with residential or commercial boilers, and producing hot water only implies that the unit functions differently than a steam-generating industrial boiler. Thus, the essential aspect of a boiler being deemed 'industrial' is its role in process-related steam generation.
