Variable throat gas turbine burnup chamber

摘要

PROBLEM TO BE SOLVED: To simply control a mixed gas ratio with high reliability in a gas turbine combustion chamber. ;SOLUTION: This chamber comprises at least one area 11 to which at least a first pilot fuel filling means 3 and a first oxidizer filling means 4 associated therewith are opened and a main combustion area 12 to which at least a second main fuel filling means 7 and a second oxidizer filling means 8 associated therewith are opened. Thus, all of them form a gas combustion chamber held under pressure P1 in a container 14. Mechanical means 15 to 19 for controlling the second flow of the oxidizer reacting to the differential pressure of internal pressure P1 and atmospheric pressure P0 outside the container 14 are included. The differential pressure is directly related to the rotating speed of an engine.;COPYRIGHT: (C)2000,JPO
