[0002] Baking the furnace is an important step in the construction of the furnace body. Its purpose is to gradually precipitate the adsorbed moisture and crystallized moisture in the refractory materials and spraying materials that construct the furnace body by slowly heating the furnace chamber through the baking furnace, thereby increasing the strength and service life of the materials, and slowly removing the moisture in the refractory masonry of the furnace body to avoid the brick lining from bursting and damaging the masonry when a large amount of moisture evaporates rapidly. When using the current furnace baking device for furnace baking operation, the burner is prone to failures such as shutdown during operation. On the one hand, special operators are required to pay real-time attention to the operating status of the burner, which results in a high labor cost.
