AGGREGATE HEATING SYSTEM AND AGGREGATE HEATING METHOD

WIPO Patent Application WO/2011/036773

A1

An aggregate heating system (20) is provided with heating furnaces (54) which heat aggregate (12) by a heating method based on microwaves, a thermal insulation furnace (52) which thermally insulates the heated aggregate by an electrical or optical heating method, and microwave supply units (62) which supply microwaves into the heating furnace, wherein the thermal insulation furnace and the heating furnaces constitute a multistage structure in the vertical direction in this order. First openable/closable aggregate discharge portions (64) which discharge the aggregate to the lower stage are provided at the partition walls separating the stages of the multistage structure, and a second openable/closable aggregate discharge portion (82) for discharging the aggregate thermally insulated in the thermal insulation furnaces is provided at the bottom of the thermal insulation furnace.
