<p>A pneumatic purge system retrofittable upon existing gas turbine engines which includes an accumulator for storing pressurized gas at the maximum pressure developed by the compressor of the turbine engine. Upon actuating a solenoid fuel shutoff valve to initiate engine shutdown, stored gas from the accumulator flows into the fuel manifold to purge fuel therefrom into the combustion chamber. Timing of the pneumatic purging sustains the combustion process to burn substantially all the purged fuel.</p> |
