What is the rated boiler horsepower for a boiler with a total capacity of 35,000 lbs/hr steam?

To determine the rated boiler horsepower from a given steam capacity, one must understand the conversion factor between pounds of steam produced per hour and boiler horsepower. One boiler horsepower is defined as the ability to produce 34.5 pounds of steam per hour.

In this case, the total capacity of the boiler is 35,000 lbs/hr of steam. To find the equivalent boiler horsepower, the total capacity should be divided by the steam production capacity of one horsepower:

35,000 lbs/hr ÷ 34.5 lbs/hr per horsepower = approximately 1,014 horsepower.

This calculation shows that the boiler's capacity of 35,000 lbs/hr translates to approximately 1,014 horsepower, making it the correct answer. Understanding this calculation is essential for assessing boiler capabilities and ensuring boilers are operating within safe and efficient parameters.
