Experimental studies of the influence of external climatic factors, taking into account exposure, on the change in the bending strength of control and microwave – treated carbon and fiberglass samples in the cured state were performed. An increase in the limit stresses of three – point bending of experimental carbon fiber samples compared to the control ones was found by 7…12 %, and fiberglassby 4…7 %. It is shown that with an increase in exposure to 14 months, the strength of control samples of carbon and fiberglass decreases by an average of 10 %. At the same time, the strength of the prototypes is reduced only by 4.4 %. With an increase in the moisture content of both control and experimental samples, a decrease in their strength is observed. In this case, the linear correlation is average (from– 0.44 to – 0.615). It is established that for experimental samples, the influence of the amount of absorbed moisture on the strength is manifested to a much lesser extent. For carbon fiber, the reduction is 16.6 %, for fiberglass – 12 %.

In the process of reception, storage and preparation of oil for processing, significant volumes of oil-containing sludge are formed, which are not only a source of pollution, but also a valuable hydrocarbon feedstock. Long-term storage of oil with water, contact with atmospheric oxygen, and the presence of solid particles hydrophobized with asphalt-resinous and paraffinous substances contribute to the formation of “intermediate layers” in these sludges, which are ultra-stable oil-water emulsions. It is proposed to use the energy of the electromagnetic field of the high and microwave ranges when developing a technology for the destruction of oil-water emulsions. After analyzing the composition of the oil sludge, experimental studies were conducted of the dielectric loss tangenttgδδ of oil with the addition of sand and paraffin, depending on the frequency of electromagnetic oscillations in the range of 30 - 160 MHz and temperature in the range of 25 - 80 ∘ С using the cumeter method. Studies have shown that two technologies for the disposal of oil sludge are possible: HF and UHF methods. To assess the effectiveness of their application, it is necessary to conduct experimental studies of the dielectric properties of oil sludge.

Abstract The article continues the study of the effect of microwave exposure on solid fuel. On the basis of the experimental studies, the dependences of changes in the temperature and humidity fields of the fuel on the time of microwave exposure, to arson, have been established. The possibility of using the microwave electromagnetic field to automate the process of burning solid fuel in a boiler plant, afterburning unburned fuel residues is considered. The mechanism and basic conditions of these processes are presented. The influence of this technology on the intensification of the fuel ignition process, its homogenization, an increase in energy characteristics and a change in the elemental composition, an increase in the efficiency of a boiler plant, a decrease in chemical, mechanical underburning and harmful emissions of a boiler plant is considered. The main conditions of the applied technology are: placement of the microwave generator on the combustion device of the boiler unit, the size of the solid fuel samples or its contacting pieces should be less than the wavelength of the microwave electromagnetic field (12.4 cm), the moisture content - within the range from 10 to 95%. The intensification of the process of burning solid fuel also depends on the type of fuel, its physical and chemical properties (various types of coal, wood fuel, including wood waste, peat, and others). Modernization of boiler plants using this technology is possible by unifying projects that take into account the correspondence of microwave generators to the thermal power of boiler units.
