GAS TURBINE COMBUSTOR CONTROL SYSTEM

摘要

A gas turbine system includes a controller (118) configured to receive fuel composition information related to a fuel (70) used for combustion in a turbine combustor (160); receive oxidant composition information related to an oxidant (68) used for combustion in the turbine combustor (160); receive oxidant flow information related to a flow of the oxidant to the turbine combustor (160); determine a stoichiometric fuel-to-oxidant ratio based at least on the fuel composition information and the oxidant composition information; and generate a control signal for input to a fuel flow control system configured to control a flow of the fuel to the turbine combustor (160) based on the oxidant flow information, a target equivalence ratio, and the stoichiometric fuel-to-oxidant ratio to enable combustion at the target equivalence ratio in the presence of an exhaust diluent within the turbine combustor.
