1. The problem statement, all variables and given/known data I have a problem which I will attach a picture of, regarding a system composing of a heat recovery steam generator and a turbine. I have to work out the power output of the turbine, which I think I will be fine with. What I would like to know is, how does the combustion products entering and exiting the steam generator affect the other input of water which also enters and exits the steam generator. I noticed that the temperature decreases when the combustion products exits the system. Does the drop in temperature mean that the heat transfers to the water flowing through the system? The combustion products are to be treated as air and an ideal gas. Thanks in advance.
