Boiler Ratings | Spirax Sarco

The ‘from and at’ rating is widely used as a datum by shell boiler manufacturers to give a boiler a rating which shows the amount of steam in kg/h which the boiler can create ‘from and at 100°C’,at atmospheric pressure. Each kilogram of steam would then have received 2 257 kJ of heat from the boiler.

what are boiler efficiency and boiler evaporation ratio
What are boiler efficiency and boiler evaporation ratio

2020-3-20 · 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.
