Substantiation of reasonability of the extension of the scope of application of the inductive heaters for heating the residential and civil buildings

Problem statement. When referencing heating, most people immediately imagine bulky boilers, a significant amount of complex bound pipes, massive radiators and so on, which is typical for a heating system that runs directly on fossil fuels. The main disadvantage of using gas in our country is the constant price increase for it, and in the current situation, any changes towards the reduction of cost are not expected. It is also possible to include the high cost of gas network connection to the objective disadvantages, reducing the gas pressure at negative temperatures due to its compression, its low quality and, as a consequence, low heating value. Electric heating can be used as an alternative to gas. It is one of the most environmentally friendly as well as convenient ways to heat the space. Currently, there is a significant variety of devices and equipment such as electric boilers of various types; electric convector heaters; electric fan heaters; oil coolers. All of them are combined by the common principle of heating. An electric current is directly sent to a fuel element, most often it is a tubular electric heater, as a result of which it is heated. TEH (tubular electric heater) is a heating element in the form of a heating coil, which is placed in a closed tube of a heat-resistant material. The operating temperature of a tubular electric heater cover on average can reach 450…500 оС. An essential disadvantage of such a method of obtaining heat is the considerable expenses of the electric power spent for heating the tubular electric heater, but at the same time only the small surface area of tubular electric heater has contact with the heat carrier. Another much more effective way of electric heating is induction heating. It consists in heating conductive bodies (fine pipes) due to the excitation of electric currents in them by an alternating electromagnetic field. The purpose of the article is to substantiate the extension of the scope of the application of the inductive heaters for heating residential and civil buildings.
