摘要
目前低变质程度烟煤制取型煤的技术还处于起步阶段.为研究终温及其保温时间对低阶煤制取型煤质量的影响,利用制取型煤和测试其强度的相关设备分别进行了不同终温温度和最佳终温下不同保温时间的单因素实验.结果表明,160℃可作为低变质程度烟煤(低阶神木煤)制取气化型煤的最佳干燥终温,干燥型煤生球的最佳终温保持时间为20 min^30 min.
In light of this situation,the technology of briquette of bituminous coal in low rank is still in the initial stage.In order to study the influence of terminal temperature and its holding time on briquette quality,a series of experiments of single factor under different terminal temperature and different holding time at the best terminal temperature were carried out under natural and saturated state by concerned equipments to manufacture briquette and determine the strength of briquette.The testing results show that 160 ℃ can be used as the best terminal temperature for drying coal briquette by bituminous coal in low rank （Shenmu coal）,and reasonable holding time of best terminal temperature is 20 min-30 min.
