[0040] The working principle and use process of the embodiment are as follows:

[0041] Sample preparation: the coal sample is respectively loaded into the volatile matter crucible 106, the ash content crucible 204 and the moisture content crucible.

[0042] Volatile matter testing process: the volatile matter crucible 106 loaded with the coal sample is placed on the volatile matter turntable body 107; the volatile matter crucible 106 is rotated to below the volatile matter heating furnace 101 by the volatile matter lifting and rotating mechanism 105; the four volatile matter crucibles 106 are simultaneously pushed into the volatile matter heating furnace 101 by the upward movement of the volatile matter sample feeding mechanism 104; heating is performed at 900℃±10℃ for 7min; after completion, the volatile matter sample feeding mechanism 104 is lowered and the volatile matter turntable body 107 is rotated; after testing, the sample is transferred to the volatile matter constant temperature furnace 103 for constant temperature; the volatile matter content is calculated by weighing with the volatile matter weighing device 109; the volatile matter heat insulation mechanism 102 controls heat loss during the testing process.

[0043] Ash test procedure: the ash crucible 204 containing coal sample is placed on the ash turntable 202; oxygen with a specified flow rate is introduced; the ash heating furnace body 201 is heated at a rate of 30-40 DEG C / min; the temperature is raised from room temperature to 500 DEG C±10 DEG C and kept; the temperature is raised from 500 DEG C±10 DEG C to 815 DEG C±10 DEG C and kept; the temperature is lowered by the ash heat dissipation device 203; the weighing is completed by the interaction of the rotary lifting mechanism of the ash section 200 and the weighing device; the burning and cooling and weighing process is repeated, and the ash content is calculated.
