Abstract
Embodiments of the present disclosure are directed towards a system including a gas turbine engine, a selective catalytic reduction system, and a control system configured to regulate operation of the selective catalytic reduction system based at least partially on preset variations in an emissions compound of exhaust gases produced by the gas turbine engine.
Claims20
A system, comprising:
- a gas turbine engine;
- a selective catalytic reduction system;
- and
- a control system configured to regulate operation of the selective catalytic reduction system based at least partially on preset variations in an emissions compound of exhaust gases produced by the gas turbine engine.
1 more element
A method of operating a turbine system, comprising:
- operating a gas turbine engine of the turbine system at less than full load;
- increasing an emissions compound in an exhaust gas produced by the gas turbine engine;
- utilizing available capacity of a selective catalytic reduction system of the turbine system to reduce the emissions compound in the exhaust gas to produce a processed exhaust gas.
A method of operating a turbine system, comprising:
- scheduling variations in a first amount of an emissions compound in exhaust gas produced by a gas turbine engine of the turbine system;
- regulating operation of a selective catalytic reduction system of the turbine system to achieve a second amount of the emissions compound in a processed exhaust gas produced by the selective catalytic reduction system based at least partially on the variations in the first amount of the emissions compound in an exhaust gas produced by the gas turbine engine of the turbine system.
