In order to reduce air pollution and achieve energy goals for energy conservation and emission reduction, most cities have started coal-to-electricity projects. The fused magnesia bricks have changed the traditional coal-fired boilers into solid electric heat storage devices that are heated by electricity. Aluminum high-purity magnesia bricks, wherein, in the solid electric heat storage device, the electric energy is converted into heat energy mainly by the heating body, and then the heat energy radiated by the heating body is stored by the heat storage brick, and when heating is required, only the heat storage brick is needed. The air is blown, and the heat in the heat storage brick is taken out by the air flow for heating.

However, the existing heat storage brick can only be installed on one side of the heating body, and the ventilation hole is provided on the side opposite to the heating body. Due to the limitation of the above structure, the number of heating bodies installed on one side is limited, and the unit time is saved. The hot brick stores less heat energy, and the heat storage speed is slow. At the same time, the ventilation channel is located on the opposite side of the heating body, and the distance is long. It is difficult to effectively carry out the heat energy in the heat storage brick, and there is a problem of low sensible heat efficiency.

Therefore, how to develop a new type of heat storage brick to solve the above problems has become an urgent problem to be solved.

Among them, in the solid electric heat storage device, the electric energy is converted into heat energy mainly by the heating body, and then the heat energy radiated by the heating body is stored by the heat storage brick. When heating is required, only the heat storage brick is blown and the wind flow is passed. Bring the heat from the heat storage bricks out for heating.
