Heat storage element, regenerative burner device including the heat storage element, and industrial furnace including the regenerative burner device

摘要

An object of the present invention is to provide a heat storage body having high heat storage and ventilation, and a regenerative burner device including the heat storage. The method is used for alternately performing recovery of heat of a combustion exhaust gas E generated when a workpiece 2 containing components scattered at a high temperature is burned and heating of combustion air A. The heat storage body 20 has a thermal conductivity greater than that of alumina, and at least its surface 21 is made of a non-oxide ceramic material. [Selection] Figure 2
