Dynamic Simulation of Fluidized Bed Combustors and its Validation Against Measurements

摘要: A dynamic mathematical model of a continuous atmospheric bubbling fluidized bed combustor (ABFBC) has been developed on the basis first principles and used to correlate data from pilot-scale combustor. The accounts for freeboard hydrodynamics, volatiles release combustion, char particles combustion their size distribution, heat transfer. solution procedure employs method lines (MOL) approach governing nonlinear partial differential equations. initial conditions required each sub-model was provided simultaneous equations with all temporal derivatives set zero. Predictive accuracy both steady state models assessed by applying it prediction behavior METU 0·3 MW ABFBC Test Rig, comparing predictions measurements taken same rig at transient conditions. Transient were obtained imposing changes ...
