In once through boilers the pressure after the economizer can be calculated by adding the pressure loss in the evaporator to the pressure after evaporator. The temperature after the evaporator is normally between 300 and 350 °C (can be chosen). Knowing the pressure and the temperature, the specific enthalpy after the evaporator can be defined.
