A Parametric Study of Spontaneous Ignition in Large Coal Stockpiles

The general guidance for storing large stockpiles of coal is to pack it to a density of 1100 kg/m 3 to 1200 kg/m 3 corresponding to porosity in the range of 0.12 to 0.13 . The experiments in Schmal et al. also show that porosity plays a significant role in the self-heating of large stockpiles of coal. The current study analyses the influence of ...

Coal Stockpile Temperature Monitoring for Spontaneous …

Monitoring Coal Pile for Early Spontaneous Combustion. Early detection is critical in preventing spontaneous combustion. The first stage of spontaneous combustion is accumulating enough heat to ignite. With the use of a FLIR thermal camera, one can spot potential problems with their stockpile or equipment before it actually starts burning.

A review on numerical solutions to self-heating of coal stockpile

A detailed examination indicates an increase in porosity of a coal stockpile could affect self-heating behaviour in four aspects: (i) attract more airflow into stockpile and thus enhance availability of oxygen; (ii) provide more convective flow within pile and hence increase heat dissipation via convection in a non-equilibrium thermal model [64 ...
