Abstract

The processes of energy exchange in mine-reconstructive electrothermal reactor are reviewed, which poses to be a reaction volume of different phase composition, in some areas where processes occur at temperatures above 2000 K. The difficulties of experimental studies cause the development of adequate numerical schemes, which are used to implement numerical methods. The proposed mathematical model allows us to describe the totality of interrelated thermal processes in the areas of different phase composition. For this purpose, one of the boundary conditions for the reaction zone is supplied to the melting condition of the feed stock reactor. Dynamic behavior of the reactor when changing control parameters, such as the composition of the charge, the voltage across the electrodes, the dosage of the reducing agent is based on the concept of virtual reality, along with the numerical values of the parameters on the computer (ECM) display is displayed in graphical form the internal structure of the furnace bath. This kind of computer simulator can be used for adaptation of the personnel in the process of control of the unit when the access is not within the scope of the reactor because of the high temperature and the reaction medium. Analysis of reactor’s modes operation as an example of production of phosphorus had shown that the processes occurring in the reaction zone have the properties of self-regulation, when the balance between phases is set depending on the power unit. Another feature of the reactor zone recovery is ambiguity stationary states, when the same power of the mass of reducing agent can be different at different dosage of the reducing agent. Parameter charts showing the dependence of technical and economic parameters to the control parameters are received in the work.

The work was made as part of the base part of the state task by the Russian Ministry of Education and Science No. 2014/123 to perform public works in the area of scientific activities, project No. 2493.
