Title:
FURNACE WALL STRUCTURE OF WET BOTTOM FURNACE, AND WET BOTTOM FURNACE
Document Type and Number:
WIPO Patent Application WO/2019/156064
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a furnace wall structure of a wet bottom furnace with which it is possible to increase the cooling effect of a refractory material without changing the total quantity of studs, and with which it is possible to reduce wall-thinning of the refractory material due to erosion. A furnace wall structure (161) of a wet bottom furnace is provided with a peripheral wall tube (162) forming a furnace wall of the wet bottom furnace, and a plurality of studs (163) which are arranged side by side on a side surface of the peripheral wall tube (162) at fixed intervals in the axial direction of the peripheral wall tube (162), in such a way as to extend in a radial direction from the center of the peripheral wall tube (162), wherein, in an arbitrarily defined plane perpendicular to the axial direction of the peripheral wall tube (162), the studs (163) that are farthest from one another are provided within an angle range of 50 to 140° around the peripheral wall tube (162).
