摘　　要：在实验室条件下研究了从低煤化度烟煤到高煤化度无烟煤,以及石油焦等不同气化原料煤的成浆性.为提高低煤化度烟煤的成浆浓度,在保证其混合原料灰熔融特征温度满足液态排渣前提下,将低煤化度烟煤与一种或两种煤化度较高的煤或者石油焦配比,考察了它们的成浆性.结果表明,煤化度适中的QD煤单独制浆浓度达到70%,黏度536mPa.s,流动性为A;通过不同煤种的级配,三种原料配合的料浆浓度为62%时,黏度在340mPa.s～550mPa.s之间,可以获得符合液态排渣气化要求的混合料水煤浆,扩大了气化原料来源.Rainging from bituminous coals that contain low degree of codification to high rank anthracite,as well as petroleum cokes for coal gasification were carried out in the lab.Under the premise of assuring the mixed coals ash fusion temperature is to meet with discharging liquid ash,some higher rank coal and/or petroleum cokes are chosen as increasing concentration of low rank CWS by blending.The slurryability of mixed coals water slurry was also investigated.The test results show that the CWS＇s concentration of high rank coal is higher than that of low rank coal,the CWS＇s concentration of middle rank coal is about 70%,the apparent viscosity is 536 mPa·s,and the flowage property is given A grade.When the CWS＇s concentration is to keep in 62%,the CWS＇s apparent viscosity of 3 kinds of feedstock blend which contains low rank coal is 340 mPa·s-550 mPa·s,and can satisfy the need of CWS＇s gasification technology of liquid ash discharge.
