DESIGN OF COOLED STACK OF BLAST FURNACE Russian patent published in 1996 - IPC

FIELD: metallurgy. SUBSTANCE: structure of stack cooling system is made in form of large-block reinforced concrete panels and thick-walled cooled pipes whose length equals cooled height of stack with combined inlet and outlets of cooling medium two sliding supports which fix the pipe position. Distance between axes of pipes equals 1.8-2.2 of the external diameter of cooling pipe, and thickness of concrete layer equals 2.5-3.5 of the external diameter of cooling pipe. EFFECT: higher efficiency. 2 cl, 1 dwg
