Title:
METHOD AND SYSTEM FOR COOLING HEATING FURNACE
Document Type and Number:
Japanese Patent JPH10246577
Kind Code:
A
Abstract:
To cool a heating furnace efficiently, and thereby economically, using a small quantity of cooling medium.
A heating furnace 1 is cooled by supplying liquid nitrogen LN2 for cooling. A primary cooling path 17a is wiped spirally around the heating furnace 1 and the LN2 flowing through the primary cooling path 17a is introduced again into the heating furnace 1 through a secondary cooling path 17b and sprayed toward the bottom face of the heating furnace 1 through the opening 17c thereof. Since the LN2 flowing through the primary cooling path 17a is not discarded, as it is, but sprayed again into the heating furnace 1, the heating furnace 1 can be cooled efficiently using a small quantity of LN2.
