The heat storage box is loaded with heat storage bodies and fire-blocking bricks, and is connected to air (or gas) pipelines and burner bricks. The heat storage box is required to have high temperature resistance and thermal insulation properties.

[0003] According to the description of a waste gas heat storage device for industrial furnaces disclosed on the patent website (authorization announcement number: CN215177018U), "The utility model discloses a waste gas heat storage device for industrial furnaces, which relates to the field of industrial furnace energy storage technology, including a heat storage chamber and a combustible gas discharge head, a waste gas inlet, a dust cleaning port, a combustible gas inlet head, a discharge port and a heat storage body. A support block is fixedly installed on the inner lower side of the heat storage chamber, and a heat storage body and a dust removal device are fixedly installed on the upper and lower ends of the support block, respectively. The dust removal device includes a scraper, a guide rod, a steel cable and a filter screen, and the filter screen is fixedly installed on the lower end of the support block; the utility model provides that when the dust cleaning port is opened for dust removal by using the dust removal device, the steel cable of the dust cleaning port is grasped and applied with force, so that the scraper is driven to move through a plurality of guide rods, and the scraper contacts the bottom of the heat storage chamber, and the dust is suspended and moved, so that it is brought to the dust cleaning port, so that the user can quickly clean the dust, and the problem of relatively difficult dust removal is solved."

[0004] In view of the above description, the applicant believes that there are the following problems:
