A heating device for heating a gas stream
A recently filed patent (Publication Number: US20230194124A1) describes a heating device for heating a gas stream. The device consists of two electric connection elements that are connected to a power source and at least one heating plate unit. The heating plate unit is made up of multiple heating plate strips that are positioned in the gas stream. Each heating plate strip has a first end area and a second end area, and adjacent strips are connected to each other through a conductive spacer structure. The heating plate strips can be either structured or flat, with the structured strips having a scalloping design and being supported by adjacent flat strips.
The conductive spacer structure includes lining plates that connect the adjacent heating plate strips and a comb structure that receives the heating plate strips. The scalloping of the structured strips corresponds to the thickness of the lining plates. The heating plate strips and lining plates are joined together through welding, soldering, or riveting in both end areas. The heating device can include multiple heating plate units, separated by an electrically insulating partition and connected to each other through a contact plate.
The patent also describes a heating system that incorporates the heating device. The heating system includes an inlet side and an outlet side, and the heating device is mounted on a permeable mounting element. The mounting element can be made of an electrically insulating, heat-resistant material and may have flow channels leading to the heating device. The mounting element can also have lateral walls that provide gas-tight enclosure for the heating device. The heating system can consist of multiple adjacent or superjacent heating units, secured against relative displacement by a bearing safety. The system may have a cover that allows the gas stream to pass through and can be placed on a carrier structure, which can include a grid structure or molded bricks.
Additionally, the patent describes a heat storage device that includes a container with a storage space for a heat storage means. The container has a heating space where an electric heating system is placed, and the gas stream flows through this space. The heating space is connected to the storage space through an open volume in the interior of the container. The heat storage device can have a carrier construction for the heat storage means, which may include a grid structure. A gas distribution space can be located below the carrier construction and connected to an opening of the container. The heat storage device can also have a discharge opening and a servicing opening that is closed by a detachable wall element.
Overall, this patent presents innovative heating devices, heating systems, and heat storage devices that can be used in various applications involving gas streams.
