Claim Text:
1. A solvent-based purge system for a combustor assembly including a fuel nozzle assembly that has a liquid fuel nozzle coupled in flow communication with a liquid fuel supply manifold and at least one fuel source, said solvent-based purge system comprising: a steam purge system comprising a steam supply source and at least one steam manifold coupleable directly to, and upstream from, the liquid fuel supply manifold, to channel steam from said steam supply source to the liquid fuel nozzle via said at least one steam manifold and the liquid fuel supply manifold; and a chemical solvent-based purge system comprising a chemical solvent supply source and at least one chemical solvent manifold coupleable directly to, and upstream from, the liquid fuel supply manifold to channel chemical solvent from said chemical solvent supply source to the liquid fuel nozzle via said at least one chemical solvent manifold and-said the liquid fuel supply manifold, wherein said steam purge system is operable after said chemical solvent-based purge system to facilitate removing chemical solvent from the liquid fuel supply manifold and the liquid fuel nozzle using steam channeled from said steam supply source via said at least one steam manifold.
