Enter the efficiency of the boiler and the fuel input rate into the calculator to determine the boiler output in BTU/hr.
Boiler Output Formula
The following formula is used to calculate the boiler output.
BO = E * FI
Variables:
- BO is the boiler output (BTU/hr)
- E is the efficiency of the boiler (%)
- FI is the fuel input rate (BTU/hr)
To calculate the boiler output, multiply the efficiency of the boiler by the fuel input rate.
What is Boiler Output?
Boiler output refers to the amount of heat energy produced by a boiler and is typically measured in BTU/hr (British Thermal Units per hour). The output depends on the efficiency of the boiler and the rate at which fuel is consumed. It is a critical factor for sizing and selecting a boiler for heating systems in residential, commercial, or industrial applications.
How to Calculate Boiler Output?
The following steps outline how to calculate the Boiler Output.
- First, determine the efficiency of the boiler (E) in percentage.
- Next, determine the fuel input rate (FI) in BTU/hr.
- Next, gather the formula from above = BO = E * FI.
- Finally, calculate the Boiler Output (BO) in BTU/hr.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Efficiency of the boiler (E) = 85%
Fuel input rate (FI) = 100,000 BTU/hr
