DEFINITIONS |
|
Annexure - IV |
|
|
|
||
Terminal Temperature Difference (TTD) - The difference between the saturation temperature determined at the heater shell pressure and the temperature of the feedwater leaving heater.
Heater Drain Cooler Approach Temperature Difference (DCA) - The difference between the temperature of the drains leaving the heater and the temperature of the feedwater entering the heater.
Temperature Rise Across The Heater (TR) - The difference between the temperature of the feedwater leaving the heater and the feedwater entering heater.
Calculations
TERMINAL TEMPERATURE (TTD)
TTD = t sat – t fw out
Where,
t sat = saturation temperature taken at the heater shell pressure, oC. t = temperature of feedwater leaving the heater, o C.
DRAIN COOLER APPORACH TEMPERATURE (DCA)
DCA = t drains - t fw in
Where:
t drains = temperature of the drains leaving the heater, o C t fw in = temperature of feedwater entering the heater, o C
TEMPERATURE RISE (TR)
TR = t fw out – t fw in
