A steam generator can be modelled by using component 5
Steam Generator (Boiler) (Component 5)
or by a combination of several of these components (to calculate effectiveness factors):
Flue Gas Zone (Component 88 - steam generator heat exchanger - flue gas zone)
Main Heating Surface (Component 89 - steam generator heat exchanger - main heating surface)
Reaction Zone (Component 90 - steam generator reaction zone)
Auxiliary Heating Surface (Component 91 - steam generator heat exchanger - auxiliary heating surface)
