Title:
HEATING FURNACE AND METHOD FOR CLEANING INTERIOR OF HEATING FURNACE
Document Type and Number:
WIPO Patent Application WO/2013/061663
Kind Code:
A1
Abstract:
For a heating furnace for which the hearth is supported by means of hearth support pillars provided in a space below the hearth, the present invention addresses the problem of efficiently and quickly removing scale and the like generated in the heating furnace and accumulating on the hearth, without providing complex equipment in the heating furnace. In this heating furnace (1), for which the hearth (10) is supported by means of hearth support pillars (15) provided in a space (S) below the hearth, the hearth is divided into multiple sections, and at least a portion of the hearth support pillars supporting the resulting hearth sections (10a) are provided with elevation devices (14). The hearth sections are raised or lowered via the hearth support pillars by means of these elevation devices, thereby forming vertical gaps between adjacent hearth sections, and the interior of the heating furnace is cleaned by way of these gaps.
