Input gas flow-lb/h
Input gas inlet temperature-F		typically 800 to 1050 F
Input steam pressure-psia
Input steam temperature-F		Input zero if there is no superheater!
Input feed water temperature-F
Input pinch point-F		typically 10-25 F but can be higher if less steam is desired
Input approach point-F		typically 10-25 F but can be higher if less steam is desired..if no economizer is required input the difference between saturation temperature and the feed water!
Input blow down-%

Note: This is a simple evaluation of an unfired gas turbine HRSG temperature profiles in the Design mode only.Heat loss used=1 %.Exhaust gas analysis used:% vol CO2=3,H2O=6.5,N2=76,O2=14.5.
