SYSTEM AND METHOD FOR REDUCING THE VISIBILITY OF EXHAUST EMISSIONS IN A GAS TURBINE SYSTEM

An emissions control system (11) for a gas turbine system (10) includes an emissions control fluid supply (50), at least one sensor (58), at least one valve (52), and a controller (44). The emissions control fluid supply (50) has one or more conduits configured to couple to one or more fluid pathways (56) of the gas turbine system (10), which are fluidly coupled to a flow path of an exhaust gas from a combustor (22) through a turbine (24) of the gas turbine system (10). The at least one sensor (58) is configured to obtain a feedback of one or more parameters of the gas turbine system (10), which are indicative of a visibility of emissions of the exhaust gas. The at least one valve (52) is coupled to the emissions control fluid supply (50). The controller (44) is communicatively coupled to the at least one sensor (58) and the at least one valve (52), such that, in response to the feedback, the controller (44) adjusts the at least one valve (52) to adjust a flow of a reducing agent from the emissions control fluid supply (50) to reduce the visibility of the emissions of the exhaust gas.
