Description

The present invention relates to a heating device for heating a gas flow, a heating system for a gas flow, a heat storage device, and a heat storage system comprising such a heat storage device. In practice, thermal energy storage devices are used to store thermal energy, and these devices can be made available, for example, in power plants as needed. Known thermal energy storage devices include a storage space in which a thermal storage medium is arranged in the form of a packing material or by means of molded bricks, and the hot air is stored (Bela The hot air flows through a heat storage medium for den. The hot air is preheated to the required temperature, for example, by an electrically operated heating device. For this purpose, extra electrical energy may be used. However, the efficiency of such heating devices does not meet the highest requirements. For heat dissipation (Entladen), or the release of heat, hot air or ambient air flows through a heat storage device, which is heated in the heat storage device and then supplied in its heated form to a consuming device, such as a turbine boiler.

Figures 1-3 show a thermal energy storage device 1 that can store excess electrical energy from highly fluctuating renewable power sources such as wind power plants or solar power systems, or from a connected power grid, in the form of high-temperature heat, and thus be used to stabilize the power grid. The stored heat can be converted into electricity at a later time, as needed, via a steam process, an ORC process, etc., or can be released indirectly in the form of steam, or directly in the form of high-temperature gas for other industrial or supply processes. Furthermore, the thermal energy storage device 1 can generate high-temperature hot air by using electrical energy, which can be used in a connected power plant or industrial process. In its broadest sense, the heat storage device 1 comprises a cubic container 2 with an interior 3 formed therein, which extends vertically between the container lid 4 and the container bottom 5 and laterally between the four side walls 6. The container 2 includes a heat storage opening 7 in a side wall 6 near the container bottom 5, an inlet/outlet opening 8 in another side wall 6 near the container bottom 5, and heat dissipation openings 9 in these side walls 6 adjacent to the container lid 4.
