Dynamic modelling and optimal sizing of industrial fire …

5/3/2018 · Gutiérrez Ortiz provided a comprehensive dynamic modelling methodology for fire-tube boilers introducing both a more complex approach (utilizing finite element methods) and a simplified model. This methodology considers all of the key physical phenomena, taking place in the boiler, and it results in a notably lower computational cost, compared to the CFD models, while providing an …

Abstract In the first part of the present work, a detailed dynamic model of fire-tube boilers equipped with stagnation point reverse flow (SPRF) combustor is implemented. Experimental data, obtained through a testing procedure, are then employed to validate the developed model. Several boiler configurations with different sizes are next considered and a PID controller is subsequently tuned for

25/2/2019 · However, utilizing this approach leads to a notable computational cost and is accordingly unsuitable for dynamic modelling which necessitates running the simulation in repetitive manner. Gutiérrez Ortiz [30] proposed a physical phenomena based model for dynamic modelling of fire-tube boilers, in which finite element method (FEM) is used for simulating the gas-side.
