摘要
通过实验确定了生物质煤基燃料炭(BCFC)的制备工艺,研究了BCFC的成型机理和燃烧特性.结果表明,BCFC的制备工艺是将禹州煤、玉米秸秆和黏结剂按照81∶6∶13的质量比混合成型,再经700℃炭化处理.生物质型煤的内部结构、禹州煤和有机黏结剂的黏结性是BCFC成型的保证.市售燃料炭在燃烧初期燃烧强度较大,但持久性逊于BCFC,这与二者挥发分、固定碳和发热量的差异有关.
The preparation process of biomass coal-based fuel charcoal（BCFC） were obtained by experimental, then its briquetting mechanism and combustion characteristics were studied. The optimal process parameters of BCFC were determined as following. Yuzhou coal, corn stalk and organic binder are mixed at a mass ratio 81： 6 ： 13, and carbonized after briquetting. The bio- briquette structure and caking property of Yuzhou coal and binder are the foundation of the BCFC briuqetting. The combustion intensity of commercial fuel charcoal is higher than that of BCFC in the initial stage of combustion, while their magnitude of combustion prolongation is on the contrary, because of the difference of their volatile mater, fixed carbon and calorific value.
