TL;DR: In this article, the authors reviewed the literature on fluidized bed waste incinerators and critically examined the parameters that govern the design and operation of these incinerators, which involves considerations of hydrodynamic (velocities, mixing), thermal (heat balances) and kinetic (reaction rate and burnout) nature.

TL;DR: In this paper, a flow model has been proposed to quantify the operation characteristics of the liquid-solid circulating moving bed (LSMWB) ReReF, which consists of two or more reaction chambers and a particle transport system.
Abstract: The liquid-solid circulating moving bed reactor is a novel one, which consists of two or more reaction chambers and a particle transport system. Particles move down to the lower reaction chamber from the upper reaction chamber through an upper conduit and to the particle transport system through a lower conduit, and then are conveyed into the upper reaction chamber through a riser. The circulating rate of particles and the flow of liquid in the two conduits are key factors to the continuous steady operation of the reactor; they can be controlled by varying operating conditions: the outlet liquid flow rate in the regeneration chamber, the outlet liquid flow rate in the reaction chamber, the inlet liquid flow rate of the reactants, and the flow rate of driving flow. A flow model has been proposed to quantify the operation characteristics of the reactor. The results predicted by the model show satisfactory agreement with the experimental data.

TL;DR: In this article, a stress distribution model based on the equations of continuity and momentum balance in the liquid-solid circulating moving bed reactor is established and used for simulations which shows that the stress concentration regions are at the coupling standpipe and the bottom of the regeneration chamber.

TL;DR: In this paper, a stress distribution model for a liquid-solid circulating moving bed reactor that consists of a bottom reaction chamber, top regeneration chamber, a coupling standpipe, a particle transportation system, and a bottom standpipe is established based on the equations of continuity and momentum balance.
Abstract: A stress distribution model for a liquid-solid circulating moving bed reactor that consists of a bottom reaction chamber, a top regeneration chamber, a coupling standpipe, a particle transportation system, and a bottom standpipe is established based on the equations of continuity and momentum balance. Simulations show that the stress concentration regions are at the bottom of the regeneration chamber and the coupling standpipe. To reduce the maximal stress and increase the operation flexibility in a reactor for the 2000-ton-per-year production of linear alkylbenzene, the regeneration chamber should have a low height-to-radius ratio (about 9), a suitable half-conical angle between 28° and 35°, and standpipe radius of about 0.05 m.
