HEAT STORAGE DEVICE, GLASS MELTING DEVICE, AND GLASS ARTICLE MANUFACTURING METHOD

WIPO Patent Application WO/2018/096863

A1

Provided is a heat storage device that can efficiently store heat in a heat storing body by utilizing exhaust gas, can efficiently heat combustion air using the heat storing body, and can suppress a situation in which the heat storing body becomes brittle. A heat storage device 10, which is for a glass melting furnace, comprises: a first heat storage chamber 11 in an upper part of which there is provided a connection port 13 for connecting to the glass melting furnace and inside of which a heat storing body 11a is disposed; a second heat storage chamber 12 which is adjacent to the first heat storage chamber 11, in an upper part of which there is provided a connection duct 14 for connecting to the outside atmosphere, and inside of which a heat storing body 12a is disposed; and a flow passage 15 that connects the first heat storage chamber 11 and the second heat storage chamber 12 to each other at the bottom of the chambers. A ratio (S2/S1) between the cross-sectional area (S1) of the first heat storage chamber 11 in a planar cross section and the cross-sectional area (S2) of the second heat storage chamber 12 in a planar cross section is 0.2-0.62.
