The ratio of the heat energy required to make steam to the heat energy supplied by the combustion of fuel in a boiler is called what?

The term that defines the ratio of the heat energy required to make steam to the heat energy supplied by the combustion of fuel in a boiler is known as the factor of evaporation. This metric is crucial in evaluating the performance of a steam boiler system.

The factor of evaporation essentially provides insight into how effectively the boiler converts the energy released from fuel combustion into usable heat for generating steam. By understanding this ratio, engineers can determine how much steam production is achieved relative to the fuel energy consumed, allowing for better management and optimization of boiler operations.

While boiler efficiency refers to the overall effectiveness of a boiler in converting fuel energy into useful thermal energy, the focus of the factor of evaporation is specifically on steam generation. Therefore, understanding this distinction is key for those involved in power engineering and boiler operations.
