The engine-recoverer of secondary energy thermal sources based on a Curie point effect for magnetic materials

Abstract

Abstract The article discusses one of the most important issues of the fuel and energy complex - the energy efficiency and the most complete use of the flue gases heat. A review of existing technologies for the heat utilization, including some designs of magneto-thermal engines, is carried out, their structural and technical characteristics are considered. A technology is proposed that ensures not only the utilization of exhaust gases from power plants, but also the application in the field of waste management, for example, increasing the energy efficiency of waste incineration technologies. The idea is to use the Curie point effect when designing a recovery engine that utilizes the waste heat of secondary energy sources. The applied potential of using the effect is based on the possibility of utilizing the heat of various secondary energy sources, such as exhaust gases of heat engines, up to low potential sources, since today there are materials that carry out a second-order phase transition already at 20 °C.
