Seven critical requirements for selecting valves for fuel system shutdown

摘要

Unlike the driver of a car equipped with an internal combustion engine, an airline pilot cannot restart a commercial aircraft's engine immediately after landing. It is critical to have fuel in the distribution manifold during engine start-up and during operation. However, residual fuel remaining in the engine's combustion chamber following shutdown may adversely impact the engine and the environment.Issues that may arise include:1.Possible damage to the turbine due to 'hot starts' caused by rich fuel 2.Increased maintenance due to fuel coking inside combustion nozzles 3.Environmental and safety concerns due to fuel leakage 4.Negative impact on the airline's earnings due to wasted fuel.
