摘　　要：The combustion performance of the blend of lignite and residue from Shenhua coal liquefaction was studied.It is found that the DTG plot for the combustion of residue of coal liquefaction has three characteristic peaks,while the DTG plot of lignite combustion has one characteristic peak.With the decreasing of the blending ratio of coal liquefaction residue to lignite the three characteristic peaks become faintness.The combustion activation energies of blended coals are calculated.Compared with the blended coals,the coal liquefaction residue has the biggest activation energy,but the lignite has the lowest one.With the blending ratio decreasing the activation energy and ignite temperature of blends decrease slightly.The maximum weight loss rate DTGmax for coal liquefaction residue is bigger than that for lignite.The combustion performance of the blend of lignite and residue from Shenhua coal liquefaction was studied.
