### Steam Boiler Evaporation

Evaporation ratio = quantity of steam generation/quantity of fuel consumed.For example quantity of steam Is 310 ton/hr and fuel is 55 ton/hr then the evaporation ratio is 5.63. Evaporation ratio is also known as steam fuel ratio.A drop in evaporation ratio indicates drop in boiler efficiency.Boiler evaporation ratio depends on fuel quality.

### [Solved] The equivalent evaporation (kg/hr) of a boiler

The equivalent of the evaporation of 1 kg of water at 100°C to steam at 100°C. Equivalent evaporation of boiler = m s ( h − h f) E n t h a l p y o f v a p o r i s a t i o n o f w a t e r a t 100 O C. Calculation: Given: m s = 2000 kg/hr, h = 2426 kJ/kg, h f = 168 kJ/kg, Enthalpy of vaporisation of water at 100°C = 2258 kJ/kg.
