Document Type and Number:
WIPO Patent Application WO/2015/075998
Kind Code:
A1
Abstract:
[Problem] To provide a duct type heat storage device which enables the replacement of all the heat storage materials to be completed in a short period of time.
[Solution] A duct type heat storage device is provided with: a vertical duct (2) which is configured in such a manner that an upper duct (3) is connected to the upper part of the vertical duct, a lower duct (4) is connected to the lower part of the vertical duct, spherical heat storage materials (11) are received in the vertical duct up to above at least the lower duct, and combustion air (A) and exhaust gas (B) are alternately caused to flow between the upper duct and the lower duct through the spherical heat storage materials; a supply hopper (12) which is provided on the vertical duct and which supplies the spherical heat storage materials to the inside of the vertical duct; an upper gate (14) which is provided in an openable and closable manner between the supply hopper and the vertical duct, holds the spherical heat storage materials within the supply hopper when closed, and drops the spherical heat storage materials into the vertical duct from the supply hopper when opened; and a lower gate (15) which is provided in an openable and closable manner at the lower end (2b) of the vertical duct, holds the spherical heat storage materials within the vertical duct when closed, and discharges the spherical heat storage material from the inside of the vertical duct when opened.
