文摘
- •
Ashes deposited on probes during Zhundong lignite combustion systematically studied
- •
Deposits on probe top were wide in sizes, rich in fluxing mineral, and sintered
- •
Low melting-point mineral, hauyne, formed at 973 K, causing significant sintering
- •
Deposits on probe side surface were fine in size, rich in Ca Mg S and sintered
- •
Dominant ash deposition mechanisms on the probe tip and side surfaces identified
