Assignee: GENERAL ELECTRIC COMPANY
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F | IPC F

Claim 16:
17. A system, comprising:
a combustion turbine;
a plurality of sensing devices;
a catalyst assembly configured to treat emission gases from the combustion turbine to meet emission targets; and
a controller configured to execute a plurality of actions to control gas concentrations and gas mass flows in the emission gases in compliance with emission targets, wherein the plurality of actions comprises:
receiving an indication that the combustion turbine is to operate in a partial or no load condition;
based at least in part on the indication, determining operation parameters corresponding to the partial or no load condition;
operating the combustion turbine in the partial or no load condition using the operation parameters, wherein adjusting the operation of the combustion turbine comprises increasing a combustion temperature of the combustion turbine by reducing a diluent flow into a chamber of the combustion turbine, increasing the combustion temperature results in an increase in a concentration of nitrous oxides (NOx) in exhaust emissions, and wherein adjusting the operation of the combustion turbine comprises increasing catalyzation in the catalyst assembly by increasing injection of a reductant or changing temperature of the reductant to treat the increase in the concentration of the nitrous oxides (NOx);
utilizing the plurality of sensing devices to measure performance-related parameters of the combustion turbine; and
adjusting the operation of the combustion turbine based at least in part on the performance-related parameters during the operation in the partial or no load condition.
