In one embodiment, a system is provided. The system includes a combustor configured to combust a fuel, and a three-way valve fluidly coupled the combustor and disposed upstream of the combustor. The system also includes a fuel circuit comprising a fuel supply, wherein the fuel circuit is disposed upstream of the three-way valve and is configured to provide the fuel to the three-way valve. The system additionally includes a fuel conduit section fluidly coupling the fuel circuit to the combustor. The system further includes an inert fluid supply configured to provide an inert fluid to the three-way valve and a compressor discharge (CPD) fluid source configured to provide a purge fluid to the three-way valve. The three-way valve is configured to purge the fuel from a first portion of the fuel conduit section by using the purge fluid.

Turbine conduit purge systems

A method of delivering a purge flow through a gas turbomachine includes generating a purge flow, guiding the purge flow through at least one of a combustor assembly and a turbine portion of the gas turbomachine, determining a cumulative purge volume passing through the one of the combustor assembly and the turbine portion of the gas turbomachine to determine a predetermined purge volume, and discontinuing the purge flow once the predetermined purge volume has passed through the one of the combustor assembly and the turbine portion of the gas turbomachine.

Method for meeting a purge flow requirement for a power plant and a power plant having a purge control system

A liquid fuel purge system is disclosed for flushing liquid fuel from the combustion chambers of a gas turbine. The liquid purge system includes a three-way valve to pass liquid fuel and, alternatively, purge air to the combustion chambers. The gas turbine may operate on liquid fuel or gaseous fuel. When the turbine is switched to burn gaseous fuel, the liquid fuel remaining in the liquid fuel system is flushed by purge air provided by a liquid fuel purge system.
