Shcherbyna V. Development of theory and improvement of technological processes in the production of building materials in high-temperature aggregates

The dissertation is devoted to creation of scientific bases and development of theories for improvement of technological processes and development of technical solutions in the use and design of energy intensive high-temperature aggregates of the cement industry. The theoretical bases are developed and the generalized model of separation of the aerosol system with the use of collections of partitioned particles is formulated. The theory of calculation was developed, the mechanism of separation and dispersion of material particles was studied, taking into account the phenomena of contact with obstacles, temperature stresses and internal pressure. The method of modeling of secondary takeoff is proposed. The analytical and numerical models of calculation of technological processes in high-temperature aggregates are expanded and supplemented. Energy zones are considered as a set of fragments and elements, with the definition of the temperature of the exhaust gas and the alternating heat loss in the environment. The regularities of the constituents of heat exchange components are determined, expedient fuel and material costs are expedient. A system theory, mathematical models and algorithms for calculating the stress-strain state of furnace units have been developed with the ability to predict the evolution of the process of cracking refractories. The system is considered in the relationship and interdependence with the initial data and constructive elements.
