Abstract

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.
