Fuel purging system for a turbine assembly

摘要

A fuel purging system for a turbine assembly includes a fuel delivery system (14). The fuel delivery system (14) includes a fuel source (38) for providing a fuel to the turbine assembly, a control valve (46) for regulating a fuel flow of the fuel, a flow divider (48) for selectively distributing the fuel to at least one combustor (24), and a combustor valve (50) located upstream of the at least one combustor (24). The fuel purging system also includes a steam source (54) for distributing a steam to the fuel delivery system (14) at a location upstream of the combustor valve (50).
