Abstract: An apparatus (112) for heating a fluid is proposed. The apparatus (112) comprises at least one electrically conductive pipeline (120) for receiving the fluid at least one electrically conductive coil (110) at least one AC voltage source (114), which is connected to the coil (110) and is designed for an AC voltage to be applied to the coil (110). The coil (110) is designed for generating at least one electromagnetic field by applying the AC voltage. The pipeline (120) and the coil (110) are arranged in such a way that the electromagnetic field of the coil (110) induces in the pipeline (120) an electrical current, which warms up the pipeline (120) by Joulean heat, which is produced when the electrical current passes through conducting pipe material, for heating the fluid.

Abstract: A method for detecting deposits in a pipe system of an apparatus is proposed, the apparatus being flowed through by a fluid. In the method it is provided that at least one microwave probe is introduced into the pipe system in such a way that the fluid flows against a window (102) of the microwave probe that is transparent to microwave radiation, and that microwaves are coupled into the pipe system by way of at least one microwave probe,wherein a reflection measurement is carried out with one or two microwave probes, and/or at least two microwave probes are introduced into the pipe system at a distance from one another and a transmission measurement is carried out, wherein a comparison of measurement data with a reference or a previous measurement is used to deduce a constriction in the pipe system segment and the free cross-section at the constriction is determined, the detection of a constriction being used to deduce the presence of deposits. Further aspects of the invention relate to a microwave probe for coupling microwave radiation into the pipe system of an apparatus and to a measuring device for carrying out the method that comprises at least one such microwave probe.

Abstract: A device (110) for heating a fluid is proposed. The device comprises at least one electrically conductive pipeline (112) and/or at least one electrically conductive pipeline segment (114) for receiving the fluid, and at least one DC current and/or DC voltage source (126), wherein respectively one DC current or DC voltage source (126) is assigned to each pipeline (112) and/or each pipeline segment (114), said DC current and/or DC voltage source being connected to the respective pipeline (112) and/or the respective pipeline segment (114), wherein the respective DC current and/or DC voltage source (126) is embodied to produce an electric current in the respective pipeline (112) and/or in the respective pipeline segment (114), said electric current warming up the respective pipeline (112) and/or the respective pipeline segment (114) by Joule heating, which arises when the electric current passes through conductive pipe material, for the purposes of heating the fluid.
