Abstract

본 발명은 간접 가열방식 석탄 건조기 제조방법에 관한 것으로 특히, 제철용 코크스를 제조할 때 코크스로에 장입되는 석탄의 수분을 일정 수준 이하로 조절해주는 간접 가열방식 석탄 건조기를 제조하는 방법에 관한 것으로, 석탄의 목표 수분량으로부터 소요되는 열량을 계산하고 소요되는 열량으로부터 스팀량을 구한 다음 소요 스팀량으로부터 스팀 튜브(2)로부터 열이 석탄에 공급되는 전열 면적으로부터 건조기 단면적과 건조기의 길이 및 전열관의 사양을 결정하고, 전열관을 건조기(1) 중심으로부터 단면적 60%에서 80%에 해당하는 거리의 원주 부근에 전체 전열관 수의 1/3을 나선형 전열관(12)으로 설치하고,건조기 드럼(13)과 나선형 전열관(12)의 중간위치에 나머지 2/3를 직선형 전열관(11)으로 설치하는 것을 특징으로 하는 간접 가열방식 석탄 건조기 제조방법을 제공한다.The present invention relates to a method for manufacturing an indirect heating coal dryer, and more particularly, to a method for manufacturing an indirect heating coal dryer that controls moisture of coal charged into a coke oven at a predetermined level or less when manufacturing coke for steel making. Calculate the amount of heat consumed from the coal's target moisture content, calculate the amount of steam from the amount of heat required, and determine the dryer cross-sectional area, the length of the dryer, and the specifications of the heat transfer tube from the heat transfer area where heat is supplied to the coal from the steam tube (2) The heat transfer tube is installed in the vicinity of the circumference at a distance of 60% to 80% of the cross section from the center of the dryer 1 by one-third of the total number of heat transfer tubes with the spiral heat transfer tube 12, and the dryer drum 13 and the spiral heat transfer tube 12 Indirect heating type coal gun, characterized in that the remaining two-thirds in the middle position of the) as a straight heat pipe (11) It provides a method of manufacturing group.
