1. What is Boiler Horsepower to Pounds per Hour Calculator?

Definition: This calculator converts boiler horsepower (BHP) to steam output in pounds per hour (lb/hr).

Purpose: It helps engineers and technicians determine the steam production capacity of boilers based on their horsepower rating.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W_s \) — Steam output (pounds per hour)
• \( BHP \) — Boiler horsepower

Explanation: One boiler horsepower is defined as the ability to evaporate 34.5 pounds of water per hour into steam at 212°F.

3. Importance of Steam Output Calculation

Details: Accurate steam output calculation is crucial for boiler selection, system design, and energy efficiency assessments.

4. Using the Calculator

Tips: Simply enter the boiler horsepower value to get the equivalent steam output in pounds per hour.

5. Frequently Asked Questions (FAQ)

Q1: What is the basis of the 34.5 factor?
A: It comes from the original definition of boiler horsepower as the evaporation of 34.5 lb of water per hour at 212°F.

Q2: Does this work for all boiler types?
A: This is a standard conversion, but actual output may vary slightly based on boiler efficiency and operating conditions.

Q3: How does this relate to mechanical horsepower?
A: Boiler horsepower is different from mechanical horsepower. 1 BHP ≈ 9.81 mechanical horsepower.

Q4: Can I convert back from lb/hr to BHP?
A: Yes, divide the steam output by 34.5 to get boiler horsepower.

Q5: What about metric units?
A: For kg/hr, multiply BHP by 15.65 (since 34.5 lb/hr ≈ 15.65 kg/hr).
