Place the ash dish containing the coal sample on the conveyor belt of the ash rapid tester preheated to (815±10) °C. The coal sample is automatically sent into the instrument and completely ashed, and then sent out, taking the quality of the residue as the quality of the coal sample. The mass fraction is used as the ash of the coal sample. The ash dish containing the coal sample is gradually sent from the outside of the furnace into a muffle furnace preheated to (815±10) °C, and is ignited and burned until the mass is constant, and the mass fraction of the residue as the coal mass is used as the coal. Kind of ash.
