Abstract
Official abstract text for this publication.
A fuel control system for a gas turbine engine that includes a primary fuel circuit, a fuel tuning circuit, a plurality of combustors connected to the fuel tuning circuit, oxygen and carbon dioxide sensors in the exhaust stream and a feedback control loop operatively connected to the fuel tuning circuit and to the oxygen and carbon monoxide sensors which serve to control the precise amount of fuel and air being fed to each one of the plurality of combustors in the engine. A parallel array of control valves in a tuning fuel circuit connect to corresponding ones of the plurality of combustors in the gas turbine engine. The fuel control system thereby “fine tunes” the amount of fuel and air being fed to each combustor using data regarding the detected oxygen and carbon monoxide concentrations in the exhaust gas as provided through a feedback control loop.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for analyzing and controlling the composition of an exhaust gas from a gas turbine engine for achieving near-stoichiometric exhaust gas recirculation which reduces NO x in combustion gases generated in and exhausted by the gas turbine engine, said gas turbine engine comprising a compressor, combustors, and a turbine, said method comprising: determining a target residual oxygen level for the combustion gases wherein the target residual oxygen level…
