“…In recent years, in the world and in Uzbekistan, scientific research on the use of solar energy in various technological processes has been conducted and practical results have been achieved. The analysis of devices for obtaining energy from biomass shows that it is necessary to solve problems such as reducing the energy capacity of the raw material processing process, optimizing the energy balance of the device, and increasing its energy efficiency [7][8][9][10][11][12][13][14][15][16][17][18][19].…”

The article presents the principle scheme of the heliopyrolysis device with a solar concentrator and the mathematical model of the equations representing the heat balance of the heliopyrolysis reactor. Based on the mathematical modeling method, the energy balance of the heliopyrolysis reactor was theoretically studied, and graphs representing the temperature change of the reactor surface were obtained when the solar radiation falling on the concentrator was Ir=600÷900 W/m2 in the climatic conditions of the region of Karshi (Uzbekistan). Based on modeling in the SOLTRACE program, the graphs of the temperature field at different points of the solar parabolic concentrator are determined to change depending on the energy of the incident solar radiation. In the experimental device, it was determined that an average temperature of 200-300 ℃ can be generated in the reactor within one hour. Experiments show that in the conditions of the city of Karshi, it is possible to create a regime of 200÷500℃ sufficient for biomass pyrolysis through a parabolic solar concentrator in the daytime mode.

The article analyses generators generating efficient electricity at low speed water and wind flows. High rotating speed generators are used in wind farms and micro-hydropower. Reduction gears are used to provide the generators with the required number of rotations. The use of reduction gears in the power system leads to a decrease in the efficiency of the system and additional capital costs. The study analyzed multipolar synchronous generators. Both generators used a permanent magnet to generate electromotive force, and the generators are distinguished by the radial and axial placement of the permanent magnets. In order to analyze the generators, virtual models were created and analyzed in the Ansys Maxwell program. The Ansys Maxwell program is used to analyze electric machines in the electromagnetic field. The use of these programs in determining the optimal size of new devices is of great importance in saving time and improving cost-effectiveness.

The article analyzes the possibilities of using wind energy in Uzbekistan and studies the possibility of using energy storage devices to build a reliable electricity supply in the regions. In areas with weak winds, a device that first stores wind energy and then generates alternating electricity has been proposed. Energy storage systems have been analyzed, and it is recommended to use mechanical energy storage systems in the energy system consisting of renewable energy sources in the Republic of Uzbekistan. It has been noted that the use of such devices is particularly effective in areas far from centralized power supply, where power supply is not available or where reliability is low. An experimental model of a mechanical energy storage device using an elastic cord braid in a storage system and some equations for its design are given. The possibility and necessity of using this storage system is highly valued in our country. Despite the low power of the original model of the device, it is possible to achieve high results in the future by conducting research in this area and changing the type and composition of the elastic cord. This article presents the results of preliminary research on the development of a new design of mechanical energy storage devices using mechanical elastic cord.
