namelists &ENVIRN and &APDATA: apparatus no. 1
Applying an exergy calculation implies that you should
specify both EXFUEL en LHV for boilers (type 1) and
reheaters (type 2) to obtain correct exergy input values.
If you don't, only the exergy rise in the apparatus will
be considered, while the exergy of the fuel should also
be considered.
