In view of electromagnetic induction heating components in the new kind of electromagnetic induction heating steam generator, come up with three different structure scheme and two kinds of materials. Set up the finite element model of electromagnetic coupling. Determine the boundary conditions of the numerical calculation. Solve the magnetic flux density along the axial in heat transfer components and positioningthe tube core. Obtain the magnetic flux density distribution nephogram and variation curve. Analyzed the magnetic flux density distributy rule of the different material and structure.The results show that the magnetic flux density distribution of the heat exchange component with carbon steel core is more uniform,and the magnetic flux density distribution of scheme 2 is more conform to the heating needs of the actual working condition,have the value of engineering application,is the optimize structure.
