Abstract—The aim of this research is to investigate the effect
of ambient air temperature on the steam generation. A
parametric study was performed based on exergy analysis to
study the impact of ambient air temperature on second law of
efficiency, irreversibility and adiabatic flame temperature of
steam generation. The results showed that at 25 percent excess
air and with the range of ambient air temperature from 25 oC
to 100 oC, the adiabatic flame temperature increases from 2015
oC to 2065 oC. Also the results showed that the second law
efficiency and irreversibility ranges from 40.295% to 40.290%
and 494.063 MJ to 494.161 MJ, respectively as the ambient air
temperature increases from 25 oC to 100 oC. It is included that
the ambient air temperature has a minimum impact on
adiabatic flame temperature and insignificant impact on both
the second law efficiency and irreversibility of overall steam
generation. Also the combustion chamber and heat transfer
sections of steam generation were studied by using exergy
analysis. It was concluded that the ambient air temperature has
a minimum impact on both combustion chamber and heat
