A variant of the use of plasmatrons for the disposal of industrial waste and the organization of non-waste production is proposed in this article, which presents the design for the functioning equipment. A computer experiment was carried out to determine the parameters of the flow of the plasma jet. The results of a computer experiment are confirmed by a full-scale experiment. Conclusions and results are of practical benefit to developers and consumers of technological equipment. Keywords: plasmatron, flow, plasma, jet, temperature, velocity

Abstract Mathematical model of a plasma installation for the production of metal powder and coating has been developed. The problem of creating an objective mathematical model of the plasma jet flow is solved, which adequately describes the real process and allows predicting the parameters of the plasma jet. The value of the temperature of the plasma jet at a characteristic point located on its axis is investigated. The computer model was verified by carrying out a full-scale experiment. Comparative analysis of the results of numerical and field experiments showed satisfactory convergence. It is shown that the temperature of the plasma jet flow obeys the normal Gaussian distribution. The research results can be used to improve processes and technological equipment.

Introduction. The problem of quick identification of fire coordinates in the premises is particularly relevant electrical activation. A number of authors focus on this problem, in particular, they analyze the method of graphic and analytic positioning (хо, уо) of the fire seat in the premises.Theoretical part. The method developed by the authors makes it possible to identify the coordinates of a fire by reading N values of temperature sensors. The method has the following features: a) it is based on the fire model obtained by R. Alpert for premises, and shows that it is necessary to take into account not just the temperature read by temperature sensors, but the value of this temperature in third power;b) it allows you to determine the coordinates of the seat of fire, not only by the increase in temperature, but also by the speed of its growth, and the result in both cases will be almost the same and independent of either the height of the premises, or time, or the form of fire.Computer experiment. To verify the obtained expression, a computer experiment was carried out using the example of a warehouse. For two A and B fire variants using R. Alpert model and the specified coordinates of the fronts, using a specially developed computer program, the dynamics of temperature increase ΔTi (t) and the rate of its change were simulated.Full-Scale experiment. The paper presents the results of a full-scale experiment in which data from 16 thermocouples showing the spread of the thermal field of fire were registered. Using this data in the computer program it was possible to set the coordinates of the fire that corresponded to the real location of the seat of fire.Conclusions. On the basis of the obtained expression it is possible to set quickly, with acceptable reliability, the coordinates of the seat of fire, which allows to forcefully activate one, two or three sprinklers that are able to fight the fire at the earliest stage with the minimum flow of fire extinguishing agent.

This article presents the main results of the study of electrophysical processes occurring in the zone of electrical processing during the cleaning of soils from oil pollution. The main conclusions are formulated about the processes occurring in the electric processing zone by changing the relative electrical resistance of the soil, which was measured using microprobe sensors. A comparative analysis of the results of a laboratory experiment on the electrochemical cleaning of contaminated soil in a tank is carried out with the results of a full-scale experiment conducted on a plot of a soil mass in real conditions, but artificially contaminated with oil products (gasoline, used oil. Using single measurements of electrical resistivity by microprobe sensors, the spread of the pollutant in the soil was clarified , the relationship between the physical properties of the array and its electrical wire is established conductive properties. Confirmed high efficiency of this type of control in the study of complex processes occurring in the contaminated ground array.
