How can a boiler's efficiency be calculated?

Calculating a boiler's efficiency is fundamentally based on the relationship between the energy input and the energy output. The formula for efficiency, which expresses this relationship as a percentage, is widely accepted in the field. By taking the output energy—what the boiler produces in useful steam or heat—and dividing it by the input energy—the energy consumed from fuel—and then multiplying by 100%, one can determine how efficiently the boiler converts fuel into useful energy.

This method provides a concrete way to quantify performance and is essential for both effective operation and ensuring compliance with energy efficiency regulations. Understanding this concept is crucial for maintaining the boiler's performance and optimizing its operation, making it a core aspect of boiler management.
