The boiler (a heat exchanger to boil liquid water) produces steam at 80 bar absolute pressure and 520 C temperature (State 1) with a mass flow rate of 30 kg/s. Steam leaving the boiler enters a high-pressure turbine (HPT) and expands to an absolute pressure of 7 bar and temperature of 180 C (State 2).

What Should The Boiler Pressure Be When The Heating Is On?

When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.

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
