Abstract
A system for a gas turbine includes a control system comprising a processor. The processor is configured to receive a signal indicating spray intercooling fluid demand of the gas turbine. The processor is configured to determine a rate of change of the spray intercooling fluid demand. The processor is configured to control flow of a nitrogen oxide (NOX) minimization fluid that reduces NOX emissions from the gas turbine based at least in part on the rate of change of the spray intercooling fluid demand.
Claims20
A system for a gas turbine, comprising:
- a control system comprising a processor configured to:
- receive a signal indicating spray intercooling fluid demand of the gas turbine;
- determine a rate of change of the spray intercooling fluid demand;
- and
- control flow of a nitrogen oxide (NOX) minimization fluid that reduces NOX emissions from the gas turbine based at least in part on the rate of change of the spray intercooling fluid demand.
A system, comprising:
- a gas turbine configured to generate power from a fuel to drive a load;
- an at least one compressor configured to compress an oxidant;
- a spray intercooling system configured to spray a spray intercooling fluid to cool the oxidant in the at least one compressor;
- and
- a controller configured to:
- receive a signal indicating demand of the spray intercooling fluid;
- determine a rate of change of the demand of the spray intercooling fluid;
- and
- control flow of a nitrogen oxide (NOX) minimization fluid that reduces NOX emissions from the gas turbine based at least in part on the rate of change of the demand of the spray intercooling fluid to account for changes in NOx emissions due to changes in power of the gas turbine.
A method for controlling a gas turbine, comprising:
- receiving, via a processor, a signal indicating demand of a spray intercooling fluid that cools an oxidant in a compressor the gas turbine;
- determining, via the processor, a rate of change of the demand of spray itnercooling fluid demand;
- and
- controlling, via the processor, flow of a nitrogen oxide (NOX) minimization fluid that reduces NOX emissions from the gas turbine based at least in part on the rate of change of the demand of spray intercooling fluid.
