The stated heat balances are based on 100% load and tropical
condition.
The mass flows and exhaust gas temperature are based on ISO
ambient condition.
* The outlet temperature of the HT water is fixed to 80°C, and
44°C for the LT water.
At different inlet temperature the flow will change accordingly.
Example: If the inlet temperature is 25°C then the LT flow will
change to (44-36)/(44-25)*100 = 42% of the original flow.
The HT flow will not change.
