An article briefly describes advantages of streamer form of corona discharge over corona discharge of direct voltage. With the purpose of confirmation of hypotheses about possibility of stabilization of discharge processes in electric fields of streamer form of corona discharge oscillography voltage and current were done, and volt amperage features at various frequencies of pulse voltage were taken. Impact of parameters of electrodes system «Potential plane with corona needles – grounded plane» to value of discharge current was studied. Outcomes of study of power features and character of change in strength of electric fields of streamer form of corona discharge are presented.

This paper presents the results of calculations to reduce greenhouse gas emissions in agricultural sectors of the Republic of Uzbekistan within the framework of the project: “Sustainable Agriculture Development and Climate Change Mitigation”. The initial data were the characteristics of the implemented installations based on renewable energy sources for the period of 2014-2018. Most of these installations were biogas settings based on the principle of anaerobic fermentation, as well as solar water heating and photovoltaic stations. The calculations were performed according to the “AMS-III.D” and “AMS-I.J” methods by the “Global Environmental Fund” experts. The developed computer programs were applied to calculate the arrival of radiation and the duration of sunshine during the year on the territory of Uzbekistan. According to the calculations, the reduction of greenhouse gas emissions was 1338840.5 tons of CO2 for the indicated period during the operation of installations based on renewable energy sources. Within the framework of this project, the total potential of generating electric energy from biogas settings and solar photovoltaic stations at the amount of 10,424 MWh was estimated.

This article provides definitions of the positive and negative effects of the use of chlorine and ozone in water disinfection and presents the methodology and results of experimental studies of the parameters of water treatment with ozone, the electrodispersion method, as well as the electrode system “potential plane with corona needles - grounded plane”. The parameters of water treatment modes were determined by the method of three variants of aerosol charge, negative, positive and bipolar. The parameters of water treatment with ozone determined on the basis of these studies were verified on the basis of experimental studies of the process of ozone effects on aerosol particles in the contact chamber. The methodology and analysis of the results of these studies are given. Based on these studies, the best ratios of the parameters of water flow, air velocity and electrical voltage were determined. The best disinfection result was determined by the charge polarities of the water aerosol.

This article presents the methodology and results of experimental studies of the parameters of the electrode system “Potential plane with corona needles - grounded plane”. The parameters of the electrode system were determined for a distance between the electrodes of 0.15 m. The parameters of the electrode system determined on the basis of these studies were verified on the basis of experimental studies of the process of trapping dust particles from an air stream. The methodology and analysis of the results of these studies are given. Based on these studies, the best ratios of the parameters of the electrode system were determined according to the highest degree of purification of the cleaned air. The difference in the distances between the needles in a row located perpendicular to the flow of the cleaned air and between the rows of needles is determined.
