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. Shell boilers are often operated

Dry Saturated Steam - an overview | ScienceDirect Topics

We require the heat in a dry-saturated-steam form at a pressure of 700 kPa with feedwater at 50°C. The heat required to raise this steam is 2558.6 kJ/kg. Therefore steam raised = 0.71 kg/kW h. In a normal shell boiler we would expect an efficiency of about 80% over the year.
