In theory, a regenerative combustion system that uses a high-performance honeycomb heat storage will make it easier to retrofit existing furnaces with higher heat recovery efficiency. The honeycomb heat accumulator can have a strong adaptability and a long service life, the heat storage heat exchange technology is widely used in industrial furnaces.Thermal shock stability .According to the heat exchange process of the regenerator, the regenerator is operated for a long time under the conditions of repeated heating and cooling, and the surface and internal temperatures are periodically changed with time, if the regenerator If the thermal shock stability does not meet certain requirements, under the effect of frequent alternating thermal expansion and contraction, the regenerator will be broken and the air flow channel will be blocked, which will increase the pressure loss and affect the heat transfer effect of the regenerator. This will cause the regenerator to fail to work properly and be forced to replace the regenerator. According to the properties of refractories, the higher the density of the material, the greater the coefficient of thermal expansion and the worse the thermal shock stability. At the same time, the density of materials with high density is generally larger and the heat storage capacity is also greater. When selecting the formula for the heat storage material, the density of the material should be increased as much as possible while ensuring the thermal shock stability of the material.
