New Jersey Third Grade Steam Engineer (1‑C Blue Seal) License Practice Exam

One Boiler Horsepower is defined as the amount of energy needed to produce 34.5 pounds of steam per hour at a pressure of 0 psig and a temperature of 212°F. This energy requirement translates to approximately 33,475 BTUs (British Thermal Units) per hour.

Understanding this relationship is crucial for anyone involved in steam operations, as it helps in the sizing of boilers and understanding their energy output. Each BTU is a measure of heat energy, and knowing how many BTUs correspond to one Boiler Horsepower allows engineers and operators to effectively gauge the performance and energy consumption of their steam-generating equipment.

Other listed values do not correspond to the accurate conversion for Boiler Horsepower. Therefore, the figure of 33,475 BTUs stands out as the standard reference in the industry.
