Karvatsky A. The thermoelectric and mechanic state of high-temperature energy-intensive industrial units

The dissertation pursuing a scientific degree Doctor of Technical Science under the speciality 05.05.13 - Machines and apparatus of chemical industry. National technical university of Ukraine "Kyiv polytechnic institute", Kyiv, 2010. The dissertation is devoted to the establishment of scientific basis for the development of the technical solutions in energy- and resource savings, to the improvement of the methods and technologies of operation and design of energy-intensive high-temperature units in non-ferrous metallurgy, electrode production and crystallization equipment for single crystal growing. They include scientifically - substantiated operation modes, conceptual designs for the modernization of operating constructions and the development of the new ones, the com-parative assessments of energy efficiency for the substantiated technical decision-making that correspond the concept of sustainable development. Comprehensive methods for experimental-numerical investigation of thermoelectric and mechanic (TEM) state of energy-intensive high-temperature industrial units have been elaborated. Theoretical bases of the direct boundary element method for boundary value problems of potential, heat transfer and thermoelasticoplasticity with consideration of complex heat exchange, phase changes and contact interaction between conjugated solids, calculation procedures of theoretical energy balances of aluminium electrolyzers and crys-tallization kilns of different capacities have been developed. Numerical models for TEM state calculations of high-temperature units, directed to the design problem solutions at the generation of new techniques and progressive technologies have been elaborated. The im-pact of the change of process variables on energy and economic operation indexes of high-temperature units have been investigated applying elaborated procedures and numerical models.
