摘　　要：结合GB/T 219—2008《煤灰熔融性的测定方法》中封碳法测定的相关要求,从灰的制备、灰锥制作、弱还原性气氛的控制、加热速度的控制、温度的准确性、托板的观察等方面探讨了在采用封碳法测定煤灰熔融性时应注意的相关问题。Combining with the relative requirements of carbon sealing method in GB/ T 219-2008 ＂Determination of fusibility of coal ash＂, and from aspects such as ash preparation, ash cone making, weakly reductive atmosphere control, heating rate control, temperature accuracy and pallet observation, the problems which need attention in determination of coal ash fusibility using carbon sealing method were discussed.

关 键 词：煤灰熔融性 封碳法 灰锥制作 弱还原性气氛 加热速度
