CERAMIC HEAT STORAGE UNIT, METHOD FOR PRODUCING CERAMIC HEAT STORAGE UNIT, AND METHOD FOR ESTIMATING COMPOSITION OF CERAMIC HEAT STORAGE UNIT

WIPO Patent Application WO/2022/270614

A1

[Problem] To provide an inexpensive, easy-to-produce ceramic heat storage unit that has high thermal efficiency even in a thermally non-equilibrium state such as a regenerative heat storage burner system and is highly maintainable because contaminants do not tend to adhere thereto and the unit is difficult to break due to excellent wear resistance, and a method for producing the ceramic heat storage unit. [Solution] The ceramic heat storage unit 10 comprises mainly alumina and is equipped with a shell 11 having an average absorbance of more than 0.3 at 1.7-2.7 μm, which is the central wavelength of radiant heat of 800-1400°C. Also, the shell 11, in addition to alumina, includes oxides including Cr, Fe, Mn, and Co in an amount of 1 wt% or more in terms of compounds. In addition, the shell 11 is a shell having a spheroidal shape, the outer surface of which includes a sphere, and having a hollow portion inside. Furthermore, in the shell 11, the core temperature of the hollow portion 12 during heat storage is higher than the inner surface temperature of the shell 11.
