The Waste Heat Recovery Unit (WHRU) and the Hot Water System are each responsible for producing and distributing water. This study presents an evaluation of the WHRU and Hot Water System to determine its ability to provide higher hot water temperature/discharge to the Reclaimer Loop Heaters. Mathematical models are used to calculate WHRU's ability to provide it at the desired temperature and discharge. Several safety-related mechanical issues will be considered in connection with the risk of evaporation, which can occur when the temperature of hot water is raised to near or above its evaporation temperature at operating pressure. Then, the Hot Water System is evaluated for its ability to deliver a higher temperature/hot water flow."
