农作物秸秆炭制备速燃炭的研究

以农作物秸秆炭为主要原料制备速燃炭,研究了秸秆炭与引燃剂的比例及成型方式对速燃炭性能的影响,结果表明,农作物秸秆炭与引燃剂质量比为4:3,块状成型方式制备的速燃炭性能较好,其燃烧热为 21289.76 J/g,且 24 g 该速燃炭燃烧时火焰持续 13 min 55 s,火星持续 113 min,燃烧残渣 13.19%。并通过燃烧实验表明, 24 g 速燃炭能使 50 mL 蒸馏水持续沸腾 17 min,且水温在60~80℃ 之间保持 90 min 以上。

Study on Preparation of Combustible Charcoal from Straw Charcoal

Combustible charcoal was prepared from straw charcoal. The effects of proportion and molding way on the properties of combustible charcoal were studied. The combustible charcoal was made under the conditions which straw charcoal and ignition agent were mixed together to form the block with the ratio of 4:3. The results showed that combustion heat was 21 289.76 J/g and 24 g combustible charcoal could burn for 13 min 55 s, spark could last for 113 min, combustion residue was 13.19%. By application of combustible charcoal 24 g to treat distilled water 50 mL, distilled water was boiled continuously for17 min and the temperature of water was keeping between 60-80℃ over 90 min.
