The results are useful to explore the basic combustion principles and the strength of the buoyancy effect on coal combustion, and to validate and develop coal combustion models for the ground coal utilization. The characteristics of coal ignition and combustion are the theoretical foundation for highly efficient and clean utilization of coal resources. This paper reviews the latest status and comments on the future prospects of the researches on microgravity coal combustion. The experimental system carried on SJ-10 satellite is also briefly introduced.
