Different from a traditional coal-fired boiler, according to a novel distributed thermal energy supply system, an electromagnetic induction heating principle is adopted, and the principle is mainly characterized in that a material to be heated is put in a high-frequency alternating magnetic field (such as a toroidal coil with an alternating current applied) to form a magnetic force line of the magnetic field to cut the material to be heated located in the magnetic field, on the cross section perpendicular to the magnetic force line, according to the Faraday law of electromagnetic induction, eddy currents are generated, and the induced eddy currents generate thermal energy on the alternating current impedance exhibited by a conductive material based on the law of Joule heating effect to heat a carrier. The technology of the novel distributed thermal energy supply system lies in how to control the alternating magnetic field so as to provide appropriate thermal energy for the heated end,and moreover, it is requi
