The mineralogy, morphology and sintering characteristics of ash deposits on a probe at different temperatures during combustion of blends of Zhundong lignite and a bituminous coal in a drop tube furnace
Zhundong lignite ash deposits were rich in fine-sized and sintered fluxing minerals.
•
The Australian bituminous coal ash deposits were rich in coarse refractory minerals.
•
Increasing the bituminous in the blends inhibited nepheline and diluted fine particles.
•
Sintering temperature increased as the ratio of bituminous in the blend increased.
•
The deposit mineralogy and morphology changed as the probe temperature increased.
