云南省焦煤和可供高炉喷吹的无烟煤、烟煤都十分缺乏,而褐煤的储量却很丰富,而且质量较好,省冶金局根据这种情况,组织了“高炉喷吹褐煤”的试验研究.本文根据褐煤性能的试验结果,来探讨高炉喷吹褐煤的可能性.一、褐煤的化学成分样品化验结果列入表1,与其他煤种比较,褐煤含水分和可燃基挥发物均很高,分别高于34%和51%.褐煤中,小龙潭褐煤的灰分较低,10.22%,灰分的CaO/SiO_2=7.46,质量较好,而且储量大,开采方便,较适合于高炉喷吹.所以本文重点对小龙潭
Yunnan coking coal and blast furnace for the injection of anthracite, bituminous coal are very scarce, and reserves of lignite is very rich, and better quality, the provincial Metallurgical Bureau, according to this situation, organized a “blast furnace injection of lignite” test This paper based on the test results of lignite performance, to explore the possibility of blast furnace injection of lignite.First, the chemical composition of lignite samples test results are listed in Table 1, compared with other coal species, lignite moisture and combustible radicals are very volatile High, respectively higher than 34% and 51% .In lignite, Little Longtan lignite ash is low, 10.22%, ash CaO / SiO_2 = 7.46, good quality, and reserves, easy mining, more suitable for blast furnace injection So this article focuses on Little Longtan
