Boilers that generate steam are called steam boilers, often referred to simply as boilers, and are mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises.

Existing resistance boilers; resistance heating elements are directly installed inside the boiler body and directly contact with water. If there is a slight problem with the water quality, scaling will occur, and then the tube will burst due to overtemperature and cause an electric leakage accident. The existing internal heating electromagnetic boiler: the outer surface temperature is super high (over 200 ℃), it can only be used as a low temperature, normal pressure hot water boiler, it cannot run stably for a long time, and the boiler thermal efficiency is low (less than 90%).

After analysis, it is found that the structure of the electromagnetic heating furnace on the existing market is that the outside is an electromagnetic induction coil, the inside of the induction coil is a steel pipe, and the inside of the steel pipe is water; as shown in Figure 1, its disadvantage is that the magnetic flux leakage is relatively serious, and its power cannot do Large and inefficient.
