Ironmaking process of blast furnace gas produced by by-product, main ingredients: CO, CO2, N2, H2, CH4 and other, the CO content of the combustible components accounted for about 25%, the content of H2 and CH4 rarely, CO2, N2 content accounted for 15%, 55%, calorific value is only about 3500KJ/m no. The fuel used for blast furnace gas composition and heating value and blast furnace, the furnace iron varieties and smelting technology, modern ironmaking production commonly used production process of large volume, high temperature, high smelting intensity, high pressure jet coal quantity, improve the labor productivity and reduces the energy consumption using the advanced production technology, but the production of blast furnace gas calorific value is lower, an increase of the difficulty of. Blast furnace gas in CO2, N2 neither participate in combustion to produce heat, also does not help burning. On the contrary, also absorb heat generated in the combustion process of a lot of, resulting in blast furnace gas of theoretical combustion temperature is low.
Tengzhou City Xiangying Analysis Technology Co., Ltd. R & D XiangyingGC7990plus online gas chromatography and determination of the blast furnace gas composition. The result is accurate and reliable. The instrument is a kind of precision and explosion-proof on-line analytical instrument. Can be used for petroleum chemical industry, chemical fiber, fertilizer, metallurgy and other industrial production process analysis and product quality continuous automatic detection, the instrument can be matched with thermal conductivity detector (TCD) or hydrogen flame detector (FID). Main technical indexes: explosion-proof grade: BF3d; analysis of component number: 1, 39 components; Determination of sample flow channels: 1, 5, expanded to 10
高炉煤气为炼铁过程中产生的副产品，主要成分为:CO、CO2、N2、H2、CH4等，其中可燃成分CO含量约占25%左右，H2、CH4的含量很少，CO2、 N2的含量分别占15%、55 %，热值仅为3500KJ/m³左右。高炉煤气的成分和热值与高炉所用的燃料、所炼生铁的品种及冶炼工艺有关，现代的炼铁生产普遍采用大容积、高风温、高冶炼强度、高喷煤粉量的生产工艺，采用这些先进的生产工艺提高了劳动生产率并降低能耗，但所产的高炉煤气热值更低，增加了利用难度。高炉煤气中的CO2, N2既不参与燃烧产生热量，也不能助燃，相反，还 吸收大量的燃烧过程中产生的热量，导致高炉煤气的理论燃烧温度偏低。
