How to Use the Boiler Feed Pump Calculator Effectively
To calculate the essential parameters for your boiler feed pump system, follow these steps:
Enter the flow rate in cubic meters per hour (m³/h). For example, 75 m³/h for a medium-sized industrial boiler or 120 m³/h for a larger system.
Input the fluid density in kg/m³. For water at 80°C, use 971.8 kg/m³.
Set the pump efficiency value (between 0 and 1). Typical values range from 0.65 to 0.85.
Specify the static head in meters, representing the height difference between discharge and suction tanks.
Enter the total pipe length in meters, including both straight runs and equivalent lengths for fittings.
Input the pipe internal diameter in meters.
Provide suction and discharge pressures in Pascal (Pa).

Frequently Asked Questions
What is the purpose of calculating Total Dynamic Head?
Total Dynamic Head calculation helps determine the total pressure the pump must generate to move water through the boiler system effectively, considering static height, friction losses, and pressure requirements.
How does pump efficiency affect power consumption?
Higher pump efficiency reduces power consumption and operating costs. A pump with 80% efficiency requires less input power than one with 70% efficiency for the same flow rate and head.
Why is flow velocity important in boiler feed systems?
Flow velocity affects friction losses and erosion potential in piping systems. Optimal velocities typically range between 1.5 and 3.0 m/s for boiler feed applications.
How often should boiler feed pump calculations be reviewed?
Calculations should be reviewed when system conditions change, such as modifications to piping, changes in operating temperature, or alterations in pressure requirements.
What role does fluid density play in pump calculations?
Fluid density directly affects the power required by the pump and the pressure head calculations. It varies with temperature, making accurate density values crucial for proper calculations.
Can this calculator be used for different types of boilers?
Yes, this calculator is suitable for various boiler types, including fire-tube boilers, water-tube boilers, and industrial steam generators of different capacities.
Optimization Tips
Regularly monitor system efficiency and adjust parameters as needed
Consider seasonal temperature variations affecting fluid properties
Account for pipe scaling and aging effects on friction factors
Maintain proper documentation of system changes and calculations
Use the calculator for both new installations and system modifications
