Abstract
A rotary charging device for a shaft furnace commonly comprises a rotary distribution configured to distribute charge material on a charging surface in the shaft furnace. A rotatable structure supports the rotary distribution means and a stationary support rotatably supports the rotatable structure. According to the invention, the charging device is equipped with an inductive coupling device including a stationary inductor fixed to the stationary support and a rotary inductor fixed to the rotatable structure. The stationary inductor and the rotary inductor are separated by a radial gap and configured as rotary transformer for achieving contact-less electric energy transfer from the stationary support to the rotatable structure by means of magnetic coupling through the radial gap for powering an electric load arranged on the rotatable structure and connected to said rotary inductor.
