[0002] A solid thermal storage electric boiler is an electric boiler that uses solid materials as a heat storage body. It converts electrical energy into thermal energy through electric heating elements and stores the thermal energy in a solid medium. When heating is needed, the stored thermal energy is released through a heat exchange process and is used for heating or industrial production. This type of boiler can usually be charged with electricity during off-peak electricity price periods, thereby improving energy efficiency and reducing operating costs. Solid thermal storage electric boilers are widely used in industrial heating (such as chemical, printing and dyeing, papermaking and other industries), civil heating (such as community central heating, hotels, hospitals, etc.) and power peak and valley regulation. With the enhancement of environmental awareness and the deepening of power reform, the market prospects of solid thermal storage electric boilers are promising, and they are expected to play an important role in energy structure adjustment, power peak and valley regulation, and environmental protection management.
