Abstract
The simultaneous heating and mixing of a fluid in a vessel with heated walls and a stirring device can lead to excessively high temperatures at the walls due to the formation of a thick boundary layer. This specification discloses a stirring paddle incorporating a heated element and mounted on a rotatable shaft. The heating element is connected in series with a rotor winding mounted on the shaft so that, when the shaft rotates, a heating current flows through the heating element.
