System and Method for Providing Highly Reactive Fuels to a Combustor

摘要

A system and related method for providing a highly reactive fuel to a combustor of a gas turbine are disclosed herein. The system includes a fuel supply system that is in fluid communication with a fuel supply. The fuel supply system includes multiple fuel circuits. Each fuel circuit individually feeds fuel to a corresponding fuel distribution manifold. The system further includes a steam injection system. The steam injection system includes at least one flow control valve that is in fluid communication with at least one of the fuel circuits. The flow control valve provides for fluid communication between a superheated steam source and the fuel circuit during both fueled operation and during non-fueled operation of the corresponding fuel circuit.

1. A system for modulating a modified Wobbe index of a highly reactive fuel, comprising:
a gas turbine having a combustor, a turbine downstream from the combustor, a gas fuel supply, a first fuel distribution manifold fluidly coupled between the gas fuel supply and the combustor and a second fuel distribution manifold fluidly coupled between the gas fuel supply and the combustor; and a heat recovery steam generator disposed downstream from the turbine, wherein the heat recovery steam generator provides a flow of steam to the first fuel distribution manifold via a first flow control valve and a flow of steam to the second fuel distribution manifold via a second flow control valve.
