Abstract
Methods and a sensor module for use in controlling operation of a gas turbine system are provided herein. The sensor module is coupled within a combustion system and is configured to obtain an aspirated exhaust sample of exhaust flowing through an exhaust duct. The exhaust is generated by the combustion system. The aspirated exhaust sample is analyzed to determine a plurality of exhaust parameters. The sensor module also controls at least one combustion system parameter in a closed loop emission control (CLEC) system based on at least one of the plurality of exhaust parameters.

A method of controlling combustion emission parameters in a combustion system, said method comprising:
- obtaining an aspirated exhaust sample of exhaust flowing through an exhaust duct, wherein the exhaust is generated by the combustion system;
- analyzing, by a sensor module, the aspirated exhaust sample to determine a plurality of exhaust parameters;
- and
- controlling at least one combustion system parameter in a closed loop emission control (CLEC) system based on at least one of the plurality of exhaust parameters.
A sensor module for use in controlling operation of a gas turbine engine system, said sensor module coupled within a combustion system and configured to:
- obtain an aspirated exhaust sample of exhaust flowing through an exhaust duct, the exhaust generated by the combustion system;
- analyze the aspirated exhaust sample to determine a plurality of exhaust parameters;
- and
- control at least one combustion system parameter in a closed loop emission control (CLEC) system based on at least one of the plurality of exhaust parameters.
A gas turbine engine system comprising;
- a combustion section configured to generate combustion gases that are directed towards a turbine section;
- and
- a sensor module for operation of a gas turbine system, said sensor module coupled within a combustion system and configured to:
- obtain an aspirated exhaust sample of exhaust flowing through an exhaust duct, the exhaust generated by the combustion system;
