By using a honeycomb block, the size and weight of the regenerative burner can be significantly reduced, and it can be used for a regenerative industrial furnace such as a ladle baking machine or a heating furnace using gas fuel. The honeycomb heat storage body produced by the company has the characteristics of good thermal shock resistance, high refractoriness, large capacity, and large heat storage capacity. Generally, it will not cause abnormal damage such as shrinkage and softening due to overheating in the regenerator room during use; Honeycomb regenerators are generally used on the lower temperature side of regenerators, and their refractoriness and heat storage are lower than those of regenerators.
