【摘要】 试验利用萘系添加剂(GN)与助剂(ST)进行复配,用复配添加剂与低变质程度煤(SF)制备水煤浆,并测定浆体性能,将制得浆体烘干后分析其总孔容积。试验结果表明:萘系添加剂与助剂ST以85∶15复配时,制得浆体的表观黏度降低23.4%,最高制浆浓度提高1%~2%,煤粒总孔容积有效降低21.8%。更多还原

【Abstract】 Naphthalene additive(GN) and additive(ST) were compounded in this study. The coal water slurry prepared by low rank coal(SF) with compounded additives was studied, the slurry ability was analyzed, the total pore volume of the coal obtained after drying was analyzed. The experimental results showed that GN and ST compound at the ratio of 85∶15, the viscosity of the slurry was decreased by 23.4 %, the highest concentration was increased 1 %~2 %, and the total pore volume of coal decreased by 21.8 % effectively.更多还原
