13 The impact of having wireless thermocouples available: Installing thermocouples in the FW heater cascade drain lines enables performance assessment of the FW heater sub cooling zone. The difference between the cascade drain temperature and the FW heater inlet temperature is called the Drain Cooler Approach (DCA) temperature. When the DCA increases significantly, it is typically caused by level control problems resulting in low liquid level inside the heater. Operating with low liquid level increases steam erosion of heater tubes, control valves and downstream piping. #OSIsoftUC #PIWorld 2018 OSIsoft, LLC 13
