Hot radiator storing yard generating-apparatus

Abstract

The ceiling portion of a building (3) of a coil yard (1) for storing temporarily hot-rolled coils (2) that is steel intermediate products as the hot radiator to be manufactured in the hot rolling facilities of an iron mill is equipped with a chimney (4) which is formed into a cylindrical portion (4a) having a lower portion formed into a substantial pyramid shape and a top portion extending upward, and a generating turbine (5) is disposed in a desired portion of that cylindrical portion. Intake ports (7) are formed in the lower end portion of the side wall of the building. The hot-rolled coils in the hot state after manufactured are sequentially delivered into the coil yard, and are accumulated and stored till they are transferred to the next step. By the heat held by the hot-rolled coils, the air to be introduced from the intake ports into the building is sequentially heated to establish an upward air flow, so that the generating turbine is rotated to perform the wind power generation by the upward air flow ascending in the cylindrical portion of the chimney. As a result, the heat, which is retained by the hot radiator produced by the heat introduction, can be effectively utilized for the power generation.

Description

technical field [0001] The present invention relates to storage of high-temperature heat-radiating objects capable of efficiently recovering the heat contained in high-temperature heat-radiating objects produced in high-temperature states in various factories and allowing them to naturally radiate and cool, and effectively using them for power generation Yard power plant. This application is based on Japanese Patent Application No. 2008-26720 filed in Japan on February 6, 2008, Japanese Patent Application No. 2008-320242 filed in Japan on December 16, 2008, and Japanese Patent Application No. 2008-320242 filed in Japan on December 19, 2008. Priority is claimed in Japanese Patent Application No. 2008-323231 and Japanese Patent Application No. 2008-332066 filed in Japan on December 26, 2008, the contents of which are incorporated herein by reference. Background technique [0002] Generally, in a steel joint venture type steel company, molten steel after steelmaking is continu...

AI Technical Summary

Problems solved by technology

However, even in the facility for manufacturing high-temperature intermediate steel products as described above, there is a limit to the amount of heat released from each intermediate steel product manufactured sequentially by one production line, and since the intermediate steel products after manufacture are shipped out sequentially, The heat released by the above-mentioned steel intermediate products in the building where the manufacturing equipment is installed is also limited

In addition, since the building that accommodates the manufacturing equipment of steel intermediate products is large-scale, the heat density in the entire building is low, and it is difficult to efficiently generate electricity

[0011] In addition, since the ventilated duct type power generation device disclosed in Patent Document 2 uses sunlight as the heat source, it does not suggest any consideration for recovering the exhaust heat released from high-temperature exothermic objects produced in a high-temperature state such as steel intermediate products.
