| PART NAME ASSIGNED BY CONTROLLING AGENCY | FUEL OIL HEAT EXCHANGER |
| SPECIAL FEATURES | WHEN THE APU IS TURNED ON, THE FUEL OIL HEAT EXCHANGER USES THE APU OIL SYSTEM TO HEAT THE FUEL AS IT FLOWS THROUGH THE ENGINE TO PREVENT THE FUEL FROM ICING. THE FUEL OIL HEAT EXCHANGER IS LOCATED ON THE RIGHT SIDE OF THE ENGINE AND IS UPSTREAM OF THE FUEL MODULE. THE OIL DISCHARGE VALVE AND THE OIL BYPASS VALVE ARE LOCATED ON THE TOP SURFACE OF THE HEAT EXCHANGER AND THE THERMAL VALVE IS LOCATED ON THE BOTTOM, LEFT SIDE SURFACE. |
| PROPRIETARY CHARACTERISTICS | PACS |
| GENERAL CHARACTERISTICS ITEM DESCRIPTION | FUEL FROM THE AIRCRAFT FLOWS THROUGH THE AIRCRAFT FUEL HOSE CONNECTED TO THE BOTTOM OF THE FUEL OIL HEAT EXCHANGER. OIL FROM THE GEARBOX FLOWS THROUGH THE GEARBOX HOSE CONNECTED TO THE TOP RIGHT INLET PORT OF THE HEAT EXCHANGER. THE OIL BYPASS VALVE ALLOWS OIL TO FLOW DIRECTLY THROUGH THE HEATER AND TO THE OUTLET PORT WHEN THE PRESSURE IS MORE THAN 30 PSI. AS THE FUEL ENTERS THE HEAT EXCHANGER, THE INTEGRAL FUEL THERMAL VALVE SENSES THE FUEL TEMPERATURE. THIS THERMAL VALVE OPENS TO ALLOW THE FUEL TO ENTER THE HEAT EXCHANGER WHEN THE FUEL TEMPERATURE IS LESS THAN 7.2 C. WHEN THE THERMAL VALVE SENSES THAT THE FUEL TEMPERATURE IS MORE THAN 23.8 C, THE VALVE CLOSES AND DIRECTS THE FUEL FLOW PATH SO THAT THE FUEL BYPASSES THE HEAT EXCHANGER CORE. THE FUEL THEN EXITS THE HEAT EXCHANGER AND FLOWS INTO THE FUEL MODULE. THE OIL DISCHARGE VALVE FORCES THE PRESSURE TO BUILD TO 10 PSI BEFORE IT IS ALLOWED TO FLOW OUT OF THE HEAT EXCHANGER. |
