Embodiment Construction
[0020] The present invention adopts the principle of electromagnetic induction heating to heat the oil transported in the heating pipeline from the inside, and the heating principle is as follows: after the alternating current is passed into the helical tubular induction coil, an alternating magnetic field will be generated in the coil, and the magnetic field The magnetic induction intensity is:
[0021] B = μ 2 nI ( cos β 1 - cos β 2 ) - - - ( 1 )
[0022] In the above formula (1), B is the magnetic induction at a certain point P inside the induction coil, μ is the magnetic permeability of the magnetic medium inside the induction ...
