Discuss the parameters of 'equivalent evaporation' and 'boiler efficiency' to evaluate the performance of boilers.

The performance of a boiler is evaluated using various parameters, among which *equivalent evaporation* and *boiler efficiency* play a crucial role in assessing the effectiveness of steam generation and energy utilization.

### Equivalent Evaporation  
Equivalent evaporation is a standardized measure used to compare the performance of different boilers operating under varying conditions. It is defined as the amount of water evaporated into dry and saturated steam at 100°C per unit mass of fuel burned. This parameter helps in normalizing the steam output of a boiler by converting it to an equivalent amount at standard conditions.

Mathematically, equivalent evaporation is given by:  
\[
\text{Equivalent Evaporation (kg/kg of fuel)} = \frac{m_s \times \left( h - h_f \right)}{2257}
\]
