Abstract
The RDF combustion was simulated by Fluent software and the results were validated against the experimental results. As the flow is two-phase, for simulating fluid flow Eulerian approach and for tracking solid particle Lagrangian approach have been used. For modeling devolatilization, the single kinetic rate devolatilization model and for modeling char burning the diffusion-kinetic surface reaction rate model have been used. For simulating fluid flow Navier-Stokes equation with favre averaging and for modeling Reynolds stress k-ε standard model have been used. It was obseved that by increasing particles diameter, maximum temperature of fluid decreases and the hot zone gets farther from the inlet. It was also observed by icreasing particles moisture maximum temperature decreases in furnace.
