摘　　要：为解决黏结性煤在干馏过程中的黏结问题,采取配煤成型方法,在实验室条件下,以某黏结性原煤为基本原料,通过配入一定比例的不黏结煤和加入适当比例的黏结剂,进行配煤成型破黏研究,重点考察了成型过程中2种原料煤的粒度和配比、黏结剂用量和成型水分等因素对配煤成型破黏效果的影响,最终确定试验煤样配煤成型破黏的最优工况。结果表明:在黏结性煤(粒径≤0.5 mm)、不黏煤(粒径≤1 mm)配比为50∶50,黏结剂用量为1.0%,成型水分为15%的条件下进行配煤成型,得到的型煤干燥后冷压强度可达363 N/个,型焦冷压强度达597 N/个,且低温干馏试验中没有黏结现象,满足了国富(GF)干馏炉的入炉要求。In order to eliminate the viscosity of caking coal during pyrolysis process, a coal blending molding mode was adopted. Under laboratory condition,one caking coal was taken as raw material,then proper proportion of non-caking coal and binder were added to the raw material. The application of blending and molding method in eliminating viscosity of caking coal was studied. The influence of particle size and ratio of two raw coals, amount of binder and water on the molding process were investigated. The results showed that, when the ratio of caking coal to the non-caking coal was 50 ： 50,meanwhile the diameter of the caking coal and non-caking coal should be ≤0.5mm and ≤1 mm respectively,the binder addition was 1.0% ,molding moisture was 15%, the cold compressive strength of dry briquette and tbrmed cake could be up to 363 N and 597 N,and there was no bonding phenomenon in the low-temperature carbonization experiment, the product met the material property requirements of Guo Fu （GF） turnace.
