The urgency of the task is to develop a heat exchanger-regenerator designed for high- temperature heating of gaseous media, which are used in various technological schemes of the petrochemical, gas processing, energy and other industries. The developed heat exchanger has high performance due to the developed heat exchange surface, reliability due to the fact that the inner and outer pipes are movable relative to each other with linear dimensions compensation, it is simple to manufacture, does not require the use of an intermediate heat carrier, can be used as a heating coolant combustion products of untreated, low-grade gaseous fuel. At the same time, it is possible to equip the developed apparatus with a convection heat exchanger for more efficient use of the heat of the fuel combustion products. The article describes the proposed design, the principle of operation of this heat exchanger-regenerator. A review of the technical literature has been carried out, the main advantages of the device are shown in comparison with the currently known domestic and foreign counterparts. The paper presents the main calculated dependencies used in the design, as well as the results of the calculations. The possibility of using the proposed heat exchanger as part of a gas turbine unit used as an autonomous power source is considered, as well as information about technological processes in which it can be used. In conclusion, we can say that the developed heat exchanger has high performance, differs in the ability to work at high temperatures without violating the integrity of the structure, does not require the use of an intermediate heat carrier, and is to be used in many industries.

Modern high-temperature materials designed to radio-engineering systems protecting from external influences are considered. The obtaining possibility of radio-transparent ceramic, consists of Willemite and Slavsonite, at a temperature of 1200 °C has been studied. It is shown that the obtained ceramic materials satisfy the radio-transparent materials requirements by dielectric characteristics (ε < 10, tgδ = 10–2 ÷ 10–4). It was established that to preserve the concomitant phases of Hannite and Zincite, which impair the dielectric characteristics of the material, it is necessary to maintain the ratio of Willemite to Slavsonite as 1 : 1, taking into account the stoichiometry of these phases. This makes it possible to obtain the radio-transparent ceramic materials of the Willemite-Slavsonite composition with a low dielectric permittivity (ε = 5.9) and insignificant dielectric losses (tgδ = 0.004).
