Fuel and oil system for gas turbine, has oil pump with outlet pipeline connected with heat exchanger, and another heat exchanger arranged in fuel rear guiding pipeline for guiding high pressure fuel pump from pump outlet to pump inlet

摘要

The system has an oil system (2) with an oil pump (6) whose outlet pipeline (7) is connected with a heat exchanger (4) of a fuel system (1), where the oil pump has another outlet pipeline connected with support chambers (9). Another heat exchanger (10) is arranged in a fuel rear guiding pipeline (11) that guides a high pressure fuel pump (5) of the fuel system from an outlet of the high pressure pump to an inlet of the high pressure pump. A bypass pipeline (13) has a regulatable/controllable blocking unit (12) for conducting the oil around the exchanger (4).
