Homework Statement
If 5% of the heat available for steam production is lost to the
atmosphere, determine the amount of steam raised per hour when the
total flow of flue gases is 1400 kmol h-1.
qmH = 1400 kmol h-1
Flue gas temperatures:
Inlet = 1832°C
Outlet = 300°C
Water temperature:
Inlet = 90°C
Steam produced at 5 barg = 159°C
Latent Heat of Steam @ 5 barg = 2085 kJkg-1 (hfg)
Specific heat capacity of water = 4.18 kJ kg-1 k-1 (Cpc)
2. The attempt at a solution:
The specific heat capacity of the flue gas is not given, therefore I am missing 'cph' and cannot use the equation below:
If I could work out the heat transfer rate then I would be able to use the equation below to find the the mass flow of the steam??
Any help would be much appreciated.
Thanks.
