The stated heat balances are based on tropical conditions.
The exhaust gas data (exhaust gas ow, exhaust gas temp.
and air consumption). are based on ISO ambient condition.
* The outlet temperature of the HT water is xed to 80°C, and
44°C for the LT water
At different inlet temperature the ow will change accordingly.
Example: If the inlet temperature is 25°C then the LT ow will
change to (46-36)/(46-25)*00 = 53% of the original ow.
The HT ow will not change.
