Webthe higher the TTD the poorer the performance of the feedwater heater. A feedwater heater is designed with a target TTD that often is around 5 °F (3 °C). The next variable to be monitored is the Drain Cooler Approach (DCA) temperature, which is a measure of how close the heater drain outlet temperature is to the feedwater inlet temperature. Web• What is TTD and DCA ? Terminal Temperature difference TTD = T sat – T fw out here, T sat = saturation temperature corresponding to the heater shell pressure. T fw out = temperature of feed water leaving the heater . Drain cooler approach DCA = T drains - T fw in Where: T drains = temperature of the drains leaving the heater. green apple scorpion 710 cartridge
