Embodiment Construction
[0016] One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, all features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such practical implementation, as in any engineering or design project, many implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints, These constraints may vary by implementation. Furthermore, it should be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.
[0017] When introducing elements of various embodiments of the present disclosure, the articles "a," "an," "the," and "said" are intended to mean that there are one or ...

The disclosure relates to systems and methods for improving combustion turbine conditioning capability. The combustion turbine control system is configured to operate the combustion turbine system (10) under partial-load or no-load conditions while meeting an emission target. The combustion turbine system (10) includes a combustion turbine, a combustion turbine controller, and sensors, catalyst assemblies, and / or other associated devices. Based on given operational constraints, such as load conditions and emission regulations, the combustion turbine controller may perform corresponding actions to control a particular gas concentration and / or gas mass flow in the exhaust gas in accordance with the emission regulations. Corresponding actions may include controlling fuel and / or diluent injection to the combustor (16) to control combustion (e.g., combustion temperature) to manage combustion gas content exiting the combustor (16), controlling a compressor discharge valve to control combustion temperature, controlling a catalyst assembly to treat exhaust gas to be released into the environment, or a combination thereof.
Description
Background technique [0001] The present disclosure generally relates to operating combustion turbines having a wide range of power outputs. More specifically, the present disclosure relates to operating combustion turbines at part load or no load conditions while meeting emissions targets. [0002] The combustion turbine combusts a mixture of compressed air and fuel to produce combustion gases. The combustion gases may flow through one or more turbine stages to generate rotational energy for use by a load, such as a generator. The combustion gases may include various combustion byproducts such as carbon monoxide (CO), nitrogen oxides (NOx), carbon dioxide (CO2), and the like. These by-products or emissions are often heavily regulated. In some cases, operating the combustion turbine with an expanded output power range may increase the operational flexibility and efficiency of the power generation system. However, the cost of additional emissions control devices to meet emis...
