<P>PROBLEM TO BE SOLVED: To construct an exhaust tower without affecting the operation of a coil yard. <P>SOLUTION: The exhaust tower 4 extending in the vertical direction is vertically installed on the outside of a building 3 in the coil yard 1 for temporarily storing hot-rolled coils 2 as hot radiators. An exhaust port 5 provided to the building 3 is communicably connected to the bottom end of the exhaust tower 4 through a connection duct 6, and a power generation turbine 7 is installed at the desired position of the exhaust tower 4. A suction port 8 is formed in the side wall of the building 3. When the hot-rolled coils 2 in hot state are conveyed in order into the coil yard 1 and stacked and stored there, the air 9 in the building 3 is heated by the heat of the hot-rolled coils 2 through convective heat transfer, and the air 9 in which a buoyancy is produced flows from the exhaust port 5 to the bottom end part of the exhaust tower 4 through the connection duct 6 to produce an air bump in the exhaust tower and rotate the power generation turbine 7 for power generation. <P>COPYRIGHT: (C)2010,JPO&INPIT |
