Abstract: A combined cycle power plant that includes a gas turbine and HRSG engaged with a steam turbine via a water steam cycle having higher and lower pressure levels. The CCPP further includes a fuel line and fuel preheater. A higher pressure feedwater line delivers higher pressure feedwater to a higher pressure feedwater branch that extends through the fuel preheater, the high pressure feedwater branch including upstream and downstream segments defined to each side of the fuel preheater. A lower pressure feedwater line delivers lower pressure feedwater to a lower pressure feedwater branch. The downstream segment of the higher pressure feedwater branch is combined with the lower pressure feedwater branch at a junction point and a combined feedwater line extends therefrom. A first heat exchanger exchanges heat between the combined feedwater line and fuel line. A second heat exchanger exchanges heat between the higher pressure feedwater branch and fuel line.

Abstract: A fuel supply system for use in a gas turbine engine is provided. The fuel supply system includes a fuel manifold, and a shutoff valve coupled in flow communication with the fuel manifold and positioned upstream from said fuel manifold. The shutoff valve is configured to actuate into a closed position when the gas turbine engine is operating at an overspeed condition. The system also includes a relief valve coupled in flow communication with the fuel manifold, wherein the relief valve is configured to release fuel from within the fuel manifold when the shutoff valve is in the closed position, and when a pressure within the fuel manifold is greater than a first predetermined threshold.

Abstract: A system and method for reducing modal coupling of combustion dynamics generally include multiple combustors, and each combustor includes multiple fuel nozzle groups for mixing fuel with a compressed working fluid prior to combustion. A fuel circuit is in fluid communication with each fuel nozzle, and orifice plates in the fuel circuit upstream from the fuel nozzles control the fuel split between the fuel nozzles in each combustor and/or between different combustors to produce a frequency difference between combustors.

Abstract: A fuel supply system includes a main fuel line path configured to route a fuel to a combustion inlet region and a secondary fuel line path fluidly coupled to the main fuel line path. The secondary fuel line path is configured to divert a portion of the fuel from the main fuel line path through a first segment of the secondary fuel line path and return the fuel to the main fuel line path through a second segment of the secondary fuel line path. An obstruction mechanism is located proximate the main fuel line path at an obstruction location and is configured to cyclically translate into the main fuel line path to cyclically alter a cross-sectional area of the main fuel line path to effectively oscillate fuel flow pressure into a combustion system.
