摘要
The paper presents a methodology and results of calculation for optimization of a horizontal fluidized-bed heat exchanger. In the fluidized bed, fine solid particles are heated by flowing hot gas. The hydrodynamics of the bed and heat transfer kinetics are described by the Kunii and Levenspiel two-phase model. As the performance index the function describing the total cost of the process is applied. The process costs are expressed in exergy units. The continuous optimization algorithm of Maximum Principle was used for calculation optimization. For the considered problem, the profile of the inlet gas temperature as well as the inlet gas total flow are searched. The analytical solution describing the temperature optimal profiles for various hydrodynamic, kinetic, and economic parameters was obtained. The results of calculations were described and discussed.
