specific requirements for low pressure heating boilers

Boiler Calculations - KTH

Thus, the pressure in steam drum (drum-type boilers) or pressure after evaporator (once-through boilers) can be calculated by adding the pressure loss over the superheater stages to the pressure of the superheated steam. 3. Specific enthalpy of saturated water and steam (in the steam drum) can be read from an h-s
