Industrial Boiler Efficiency Calculation & Factors ...

Boiler efficiency measures the relationship between the energy input and energy output of a boiler system. This ratio is expressed as a percentage and is used to assess the performance of the boiler and the burner as a means to determine the fuel costs of your boiler equipment investment. In fact the ongoing fuel usage costs are the most significant portion of your investment even more than your

Gas-Fired Boilers | Building America Solution Center

The lowest efficiency boilers are atmospherically vented Category I boilers. A Category I boiler operates with the flue at negative pressure with respect to the combustion appliance zone (CAZ) i.e. the room in which the boiler is located and the stack temperature is above 140°F which is hot enough to avoid condensation in the vent. The burner draws its combustion air from the CAZ.
