Document Type and Number:
WIPO Patent Application WO/2018/230180
Kind Code:

Abstract:
The present invention effectively prevents in-furnace high-temperature gas from leaking out of the furnace through a furnace body opening, and prevents out-of-furnace normal-temperature air from entering through the furnace body opening. A central air outlet 4 for forming an airflow curtain Ca in an object passage area in a furnace body opening 2 is provided as an air outlet for forming an airflow curtain, as are left and right side air outlets 5 for each forming an airflow curtain Cb in respective gaps between left/right side walls and the object passage area in the furnace body opening 2. From the central air outlet 4, an airflow curtain-forming airflow fa blows out toward the furnace interior at downward tilted orientation having an angle of tilt θa of less than 40° relative to the horizontal. From the left and right side air outlets 5 each, an airflow curtain-forming airflow fb blows out toward the furnace interior at a downward tilted orientation having an angle of tilt θb of more than 60° relative to the horizontal, or vertically downward.
