What are steam generators often rated in terms of?

Steam generators are typically rated based on their continuous steam output, which is measured in kilograms per hour (kg/hr). This measurement reflects the amount of steam the generator can produce sustainably over time under specified operating conditions. This rating is crucial for determining the adequacy of a steam generator for particular applications, ensuring it can meet the demands of the system it serves without being overwhelmed or underperforming.

The continuous steam output is a key performance indicator that helps engineers assess not only the operational capabilities of the generator but also its efficiency in converting fuel into usable steam. Recognizing the steam output allows for better planning and operation within industrial processes that rely on steam for heating, driving turbines, or other applications.

In comparison, while maximum temperature, boiler horsepower, and heat recovery efficiency are important metrics in evaluating steam systems, they do not directly represent the generator's capacity to produce steam over a specified duration, which is why continuous steam output is the most relevant rating for steam generators.
