TUYERE PART STRUCTURE OF VERTICAL FURNACE, VERTICAL FURNACE AND MANUFACTURING METHOD OF CARBONIZATION PRODUCT MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a tuyere part structure of a vertical furnace that improves temperature of a portion far from a tuyere in horizontal direction in a vertical furnace without excessively enhancing temperature of heat medium gas blown into the vertical furnace, and thereby enables a molding to easily reach temperature of 660°C or higher during carbonization.;SOLUTION: A tuyere part structure 31 of a vertical furnace includes a tuyere 32 penetrating through a furnace wall 1a of the vertical furnace 1, and a heat conductive material 33 attached to the inner wall of the vertical furnace 1 so as to extend in a horizontal direction along the inner peripheral surface of the vertical furnace 1 from a tuyere part 32a. The heat conductive material 33 has a heat conductivity of 20 W/(m k) or more at 850°C.;COPYRIGHT: (C)2016,JPO&INPIT
