PROCESS TO CLEAN GAS TURBINE FUEL CHAMBER COMPONENTS

摘要

A method for conveying a chemical solution containing a phosphonic acid as an iron dissolving agent through the quaternary annulus chambers in forward combustion cans of a gas turbine to dissolve the iron oxide deposits and thereby facilitate cleaning of the internal fuel pathways. The method uses a cleaning flange attached to the quaternary fuel flange that has a flow directing baffle that enters the quaternary fuel orifice and directs the flow of cleaning solution in one direction in the quaternary annulus chamber.
