The stated heat balances are based on tropical conditions.The exhaust gas data (exhaust gas flow, exhaust gas temp.
and air consumption). 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)*00 = 42% of the original flow.
If the temperature rises above 36°C, then the L.T. outlet will rise acordingly.
