Abstract
A cleaning method for a flame detector of a gas turbine activating combustor, comprising branching control air for forcing a spark plug of an ignition system into the gas turbine activating combustor, and blowing the branched control air against the respective inner surfaces of light sensor glasses of a flame detector, thereby blowing off dust or soot from the glass.
Claims2
A cleaning method for a flame detector of a gas turbine activating combustor, comprising:
- branching control air for forcing a movable spark plug into the gas turbine activating combustor;
- and
- blowing the branched control air against surfaces of light sensor glasses of a flame detector, thereby blowing off dust or soot from the glass.
A cleaning apparatus for a gas turbine activating combustor flame detector, comprising:
- a spark plug to be moved by an air cylinder;
- a control air system for supplying air to the air cylinder, to thereby push the spark plug into the gas turbine activating combustor;
- a branched air system branching from the control air system;
- and
- blowing means for making air from the branched air system blow onto light sensor glasses.
