The heating element may include at least one sheath sized to fittedly engage around an outer circumference of the FDM printer nozzle; at least one wire coil at least partially contacting an inner diameter of the sheath; and at least one energy receiver associated with the at least one wire coil.

A method of improving natural gas recovery from a subterranean hydrocarbon reservoir includes at least one renewable energy source that is electrically coupled with a heat conducting element. The heat conducting element is positioned in a perforated section of a wellbore that traverses into the subterranean hydrocarbon reservoir. A temperature of the subterranean hydrocarbon reservoir is maintained above a cricondentherm temperature so that liquid condensation may be prevented at a final production time. In order to maintain the temperature within a required temperature range, an internal temperature, an internal pressure, and a set of reservoir properties are monitored and then utilized to plot a phase diagram that can be used to detect liquid condensation. If liquid condensation is detected, an electrical output of the renewable energy source is adjusted in order to control the temperature of the subterranean hydrocarbon reservoir at a producing end of a production tubing.

An induction hob includes a main body with an upper main surface on which in use at least one pan to be heated can be placed, and a lower main surface. The induction hob also includes at least one inductor coupled to the main body at the lower main surface, and a flexible body, fixed to the lower main surface. The flexible body has alternating first, electrically insulating layers and second layers each including at least one electrically conductive track. The inductor has a plurality of such electrically conductive tracks, which are positioned at different second layers and are electrically connected to each other in series and/or parallel to form a plurality of loops.

A method for assembling an induction heating device includes the steps of interposing at least one ferrite bar between a coil assembly and a support plate, and snap engaging a central polymeric fastening element on the support plate. At least one end of the ferrite bar is inserted in a radial seat of the central polymeric fastening element. The coil assembly is snap engaged with the central polymeric fastening element in order to sandwich the ferrite bars between the support plate and the coil assembly.

Multiple temperature-control process for stators (7) and rotors of electric motors and components consisting of materials with different magnetic properties by means of a triplex furnace (1) for the quick, efficient, and uniform heating-up of preferably tubular components such as stators (7), wherein the magnetic parts of a component are primarily heated up by means of induction and at the same time non-magnetic parts of the same component are primarily heated up by means of infrared radiation, and at the same time and subsequently secondary heating takes place by means of convection, in particular by passive heating elements (10), which serves for finely adjusting the target temperature and for maintaining it.

A laundry treating apparatus includes a cabinet, a drum provided inside the cabinet and formed of a metal material for accommodating a treatment target, and an induction module spaced apart from an outer circumferential surface of the drum at a predetermined interval, inducing and heating the drum, where the induction module includes a base housing for accommodating a coil, a permanent magnet housing coupled with the base housing and provided with a holder in which a permanent magnet is accommodated, and a cover housing coupled with the permanent magnet housing, and the cover housing is coupled to the permanent magnet housing and therefore the permanent magnet is located between the permanent magnet housing and the cover housing. A joint force of the induction module may be enhanced to improve durability, and noise caused by vibration of a tub may be avoided.

An induction coil arrangement is provided for use in inductive transfer of power to an object that is formed of or contains a ferromagnetic material. The induction coil arrangement has an induction coil and a support to which the induction coil is mounted to support the induction coil. The support is flexible so as to allow the induction coil to move. The support has a plurality of permanent magnets arranged such that, when an object that is formed of or contains a ferromagnetic material is placed over the support, the permanent magnets interact with the ferromagnetic material of the object to move the induction coil relative to a said object so as to centre the induction coil relative to the object.
