Abstract
A heated rotor is provided to heat and circulate a substance comprising a shaft and at least one electrically heated rotor member supported on the shaft. The rotor member comprises an outer electrically conductive casing and at least one inner electrical conductor, electrically insulated from the casing. The or each inner conductor is electrically connected to the outer electrically conductive casing at an unsupported extremity of the rotor member. The shaft provides separate electrical connections to the or each inner conductor and the casing to enable an electric heating current to flow in the inner conductor between the or each unsupported blade extremity and the shaft.
