Abstract
A chimney has a lower portion substantially in the shape of a pyramid and an upper portion forming a cylindrical portion that extends with a predetermined dimension upwardly and is provided in a ceiling portion of a building of a coil yard that is used for temporary storage of the hot-rolled coil which is an intermediate iron and steel product acting as a high-temperature heat radiator that is manufactured using the hot-rolling equipment of an iron and steel mill. A power generating turbine is provided at a predetermined position in the cylindrical portion. An intake duct is provided on a lower end portion of the side walls of the building. Hot-rolled coils that are in a high-temperature condition after manufacture are successively imported into the coil yard and accumulated and stored until transfer to a subsequent processing step. An ascending airflow is generated by sequential heating of air introduced into the building from the intake duct using heat retained in the hot-rolled coils. The power generating turbines are rotated by the ascending airflow passing through the cylindrical portion of the chimney to thereby execute wind power generation. As a result, the heat retained in the high-temperature heat radiator manufactured by introduction of heat can be efficiently used.
