1. What is a Boiler Horsepower to lb/hr Calculator?

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

Purpose: It helps engineers and technicians determine steam flow rates based on boiler capacity.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Steam Flow Calculation

Details: Accurate steam flow calculations are essential for boiler sizing, system design, and operational efficiency.

4. Using the Calculator

Tips: Simply enter the boiler horsepower value. The result will show the equivalent steam flow in pounds per hour.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 34.5?
A: This is the standard definition of boiler horsepower - the ability to evaporate 34.5 pounds of water per hour at 212°F.

Q2: Does this apply to all boiler types?
A: Yes, this is a standard conversion regardless of boiler type, though actual output may vary based on efficiency.

Q3: How accurate is this conversion?
A: This is a theoretical conversion. Actual steam production depends on boiler efficiency and operating conditions.

Q4: Can I use this for feedwater calculations?
A: Yes, but remember to account for blowdown and other system losses in actual applications.

Q5: What's the difference between BHP and regular HP?
A: Boiler horsepower is a specific measurement of boiler capacity, while mechanical horsepower measures work output.
