<P>PROBLEM TO BE SOLVED: To efficiently increase the temperature of the air in a building. <P>SOLUTION: The bottom end of an exhaust tower 4 extending in the vertical direction is allowed to communicate with the ceiling center portion of a building 3 of a coil yard 1 for storing temporarily hot-rolled coils 2 as hot radiators, and a generating turbine 5 is disposed in the desired portion of the exhaust tower 4. Air ducts 7 for flowing the air 8 horizontally along the inner surface of the side wall 6 of the building 3 are disposed on the side wall so that the inflow direction of the air 8 into the building 3 is aligned with the clockwise direction when viewed from above. When the hot-rolled coils 2 in hot state are conveyed into the coil yard 1 and stacked and stored, the air 8 in the building 3 is heated by the heat of the hot-rolled coils 2 through convective heat transfer, and the air 8 in which a buoyancy is produced flows to the exhaust tower 4 to rotate the generating turbine 5 for power generation. In this case, a swirl flow is produced in the building 3 by the air flowing from the outside into the building 3 through each air duct 7 to increase the heat exchange time of the air 8 in the building 3 with the hot-rolled coils 2. <P>COPYRIGHT: (C)2010,JPO&INPIT |
