Methods of Estimating Steam Consumption | Spirax Sarco

Dry saturated steam at 3 bar g is used to heat water flowing at a constant rate of 1.5 l/s from 10 C to 60 C. hfg at 3 bar g is 2 133.4 kJ/kg, and the specific heat of water is 4.19 kJ/kg °C Determine the steam flowrate from Equation 2.6.7:

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.
