WebThe boiler plays a critical role in the transient response of the power plants. To study the impact of load following, nonlinear models for separation drum and vertical tubes were integrated and a dynamic model of a subcritical natural circulation boiler was developed (Marchetti et al., 1999).
WebDue to the simplified assumptions or unascertained equipment parameters, traditional mechanism models of boiler system in coal-fired power plant usually have predictive errors that cannot be ignored. In order to further improve the predictive accuracy of the model, this paper proposes a novel recurrent neural network-based hybrid modeling method for … low ground palmsWebHowever, boiler models suitable for such investigations are scarce in the literature. This paper presents a mixed standard lumped model representing the boiler-drum dynamics and a 1-dimensional distributed model based on two-phase thermal hydraulic stability code to represent dynamics of evaporator sub-system.
