SIMULATION OF WORKING PROCESSES IN THE PYROLYSIS PLANT FOR WASTE RECYCLING
R. D. Iskovych-Lototsky, Y. V. Ivanchuk, Y. P. Veselovsky
This article is devoted to theoretical investigation of thermal physical processes as the main working processes in a pyrolysis plant for waste disposal by the numerical simulation. Based on the developed to a certain CAD-system KOMPAS-3DV16 three-dimensional model of a pyrolysis plant, in the software package FlowVision 3.09.04 finite-volume element method defines the main dependence thermal and hydrodynamic parameters that allowed us to estimate the effectiveness of the developed design of heat exchangers and combustion chambers, post-combustion, cooling the pyrolysis plants waste and identify further promising directions for their improvement and modernization.
Keywords: modeling, finite-volume elements, temperature, combustion, heat transfer, recycling.
