A mathematical model is developed that represents a first approximation of the dynamics of the coal char combustion. The model determines a range of particle sizes and gas temperatures where oscillation can occur and propagating spherical waves surround the particle. It is also possible to compute t

The incompleteness of our knowledge of the factors determining the behavior of coal during its combustion or gasification is continually being emphasized, e.g., [1]. One of the major reasons remains the lack of reliable experimental data on the combustion of a single coal particle. A number of metho

Continuous mass versus time data for single coal particles from 5.3 to 9.9 mm with gas temperatures of 900-1200K, Reynolds numbers of 63-126, and oxygen concentrations of 4.5-21% are presented. Devolatilization and char burn models for millimeter sized particles are formulated and compared with the
