Title:
OPERATION METHOD FOR TURNING APPARATUS FOR CONTROLLING AMOUNT OF INCORPORATION OF COMBUSTION AIR OF GAS TURBINE COMBUSTION APPARATUS
Document Type and Number:
Japanese Patent JP3163202
Kind Code:
B2
Abstract:
PURPOSE: To ensure an adjustment and control of the amount of loading of combustion air with a simplified structure by controlling a communication opening between a valve and a combustion chamber head in a control piston, and applying pressure of primary air dominating the head to a piston surface free with respect to a casing, and further applying chamber pressure dominating the combustion chamber to an opposite side.
CONSTITUTION: A control piston 8 is movable axially in a casing 10 with one side thereof to which a load of a spring 11 is applied, and is operated with a difference pressure between primary air pressure and surrounding pressure produced on a spring side controlled by a valve. Further, the control piston 8 controls openings 12, 13 for communicating between the valve 14 and a combustion chamber head 1 wherein primary air supplied from pressure produced on the head 1 is applied to one side of a piston surface free with respect to the casing, while chamber pressure produced in a combustion apparatus is applied to an opposite side thereof. Hereby, an adjustment of a loading amount of the combustion air without any trouble can be kept with a simplified structure.
