Abstract
본 발명은 개량열탄과 이 열탄의 제조방법에 관한 것으로, 국내에서 폐기처리되는 각종 나무들을 주원료로 하고 여기에 무연탄 및 탄산칼슘을 각각 10~14:6~8:1~2중량비율로 혼합하여 소맥풀을 탄산 칼슘대비 7~9중량비율 첨가하고 나서 질산바륨을 탄산칼슘대비 5~7중량% 첨가하여 혼합 후 성형 건조시켜 제조하는 것이며, 연소시 유해가스가 발생하지 않아 이상적인 연료일 뿐만 아니라 제조단가가가 저렴하고 거의 수입에 의존하고 있는 톱밥열탄을 대체할 수 있는 특징을 지니고 있다.The present invention relates to an improved hot coal and a method for producing the hot coal, wherein various woods disposed of in Korea are treated as main raw materials, and anthracite and calcium carbonate are mixed in a ratio of 10-14: 6-8: 1-2 by weight, respectively. It is manufactured by mixing the wheat grass with 7 ~ 9 weight ratio of calcium carbonate and then adding barium nitrate 5 ~ 7% by weight of calcium carbonate, mixing and molding and drying it. It has a feature that can replace sawdust coal, which has a low price and almost depends on imports.
