Title:
FUEL SUPPLY CONTROL SYSTEM FOR GAS TURBINE INCLUDING PLURALITY OF SOLENOID VALVES
Document Type and Number:
Japanese Patent JP2003336844
Kind Code:
A
Abstract:

To provide a fuel flow control system for use with a gas turbine.

The fuel supply control system 30 for a gas turbine includes a plurality of solenoid valves 52, 54 and 56. The solenoid valves are energized in a timing sequence with a phase relationship designed to achieve a desired fuel flow. In one example, one solenoid valve 52 is associated with a primary portion 60 of a fuel manifold 44 while at least two other solenoid valves 54 and 56 are associated with a secondary portion 62 of the manifold 44. A controller 32 that energizes the solenoid valves to achieve the desired fuel flow can receive feedback information regarding the performance of the turbine 20 to make adjustments to the solenoid operation to bring the performance of the turbine 20 closer to a desired level.
