Experimental investigation of ignition behavior for coal rank using a flat flame burner at a high heating rate

- Ignition for different ranks and sizes is investigated under high heating rate.
- Med-, high-volatile bituminous coal in 150-200, 75-90 μm undergo homogeneous ignition.
- High volatile bituminous coal undergo homogeneous ignition at <45 μm.
- Medium volatile bituminous coal underwent heterogeneous ignition at <45 μm.
- Anthracite and lignite coals with sizes in 150-200 μm fragmented during ignition.
