Abstract
An electrical heating system includes a magnetic core at least partially surrounded by a primary winding sized to receive a power level of greater than 1 MW. A core flow member is magnetically coupled to and positioned to surround a portion of the core, the core flow member including a core inlet and a core outlet. An external flow member is positioned outside of the core and cooperates with the core flow member to define a secondary winding. The external flow member includes an external inlet and an external outlet. A first joint is positioned to connect the core outlet and the external inlet and includes a first manifold portion fixedly connected to the core outlet to receive a heating fluid from the core flow member, the first manifold portion including a discharge arranged to discharge the heating fluid, and a second manifold portion fixedly connected to the external inlet to deliver the heating fluid to the external flow member, the second manifold portion including an intake arranged to receive the heating fluid, the second manifold portion connected to the first manifold portion. An electrical conductor is connected to each of the first manifold portion and the second manifold portion, the first manifold portion, the electrical conductor, and the second manifold portion cooperating to form a continuous electrical flow path sized to pass at least 10 kA of electrical current. An external flow connector is fixedly connected to the discharge and intake. The first manifold portion, the external flow connector, and the second manifold portion cooperating to form a continuous fluid flow path between the core outlet and the external inlet, where the heating fluid passes through the core flow member and the external flow member and is heated in response to a flow of secondary current in the secondary winding which is induced by the flow of power in the primary winding.
