Abstract
A fuel purging system for a turbine assembly includes a fuel delivery system. The fuel delivery system includes a fuel source for providing a fuel to the turbine assembly, a control valve for regulating a fuel flow of the fuel, a flow divider for selectively distributing the fuel to at least one combustor, and a combustor valve located upstream of the at least one combustor. The fuel purging system also includes a steam source for distributing a steam to the fuel delivery system at a location upstream of the combustor valve.
Claims20
A fuel purging system for a turbine assembly comprising:
- a fuel delivery system comprising:
- a fuel source for providing a fuel to the turbine assembly;
- a control valve for regulating a fuel flow of the fuel;
- a flow divider for selectively distributing the fuel to at least one combustor;
- and
- a combustor valve located upstream of the at least one combustor;
- and
- a steam source for distributing a steam to the fuel delivery system at a location upstream of the combustor valve.
A method of purging fuel from a turbine assembly comprising:
- providing a fuel delivery system having a fuel supply and a combustor valve located upstream of a combustor;
- providing a steam source;
- operably connecting the steam source to the fuel delivery system;
- and
- selectively delivering a steam from the steam source to the fuel delivery system at a location upstream of the combustor valve.
A method of purging liquid fuel from a turbine assembly comprising:
- providing a liquid fuel delivery system having a liquid fuel supply, a liquid fuel control valve, and a combustor valve located upstream of a combustor;
- providing a steam delivery system having a steam source and a steam control valve;
- operably connecting the steam delivery system to the liquid fuel delivery system;
- and
- selectively delivering a steam from the steam delivery system to the liquid fuel delivery system at a location upstream of the combustor valve.
