A system and method for configuring a boiler combustion model are provided. The system for configuring the boiler combustion model may include a model generator configured to generate the boiler combustion model using, as input/output data, data obtained based on measured data, analysis data, and controller information, a model simulator configured to simulate the generated boiler combustion model and output simulated results, and a model modifier configured to evaluate the boiler combustion model based on the simulated results and generate modification information for modifying the boiler combustion model based on the generated boiler combustion model and corresponding evaluated results.

The combustion apparatus includes a burner configured to generate flame, an ignition section configured to generate spark for igniting the burner, a flame detection section configured to detect the presence or absence of the flame of the burner, and a flame determination section configured to determine, based on a detection result of the flame detection section in a preset determination period, whether or not the flame is generated at the burner. When a predetermined condition is satisfied based on the detection result of the flame detection section in the determination period, the flame determination section determines that the flame is generated. The ignition section generates the spark across a particular period, in which the predetermined condition is not satisfied, of the determination period, and does not generate the spark in the remaining period of the determination period.

The invention discloses a system for effecting a control strategy in a reactive flow field of a turbulent flow system. The system is configured to analyze flow field properties such as velocity, heat release rate, or mixture fraction of a device during the onset of the oscillatory instability using measures from complex network theory such as betweenness centrality, degree, or closeness. The system identifies critical regions in the flow field responsible for the oscillatory instability. Further, the system also identifies optimal control strategies to avoid the onset of oscillatory instabilities by analyzing the relative strength of various network parameters and thereby controlling oscillatory instabilities which are detrimental to the fluid dynamic system. The disclosed method and system provide for optimization of control of oscillatory instabilities in fluid dynamic systems.
