Coal Stock Pile Spontaneous Combustion Early Detection

Coal Stock Pile Spontaneous Combustion Early Detection

Spontaneous combustion is a common occurrence when storing coal for extended periods of time. This may also be problematic when stockpiling waste/spoil materials that contain large quantities of coal. Early detection and prevention of spontaneous combustion is critical in order to prevent serious incidents occurring.

Derek Stuart Global Product ManagerPower looks at why early detection of potential spontaneous heating and combustion locations in coal milling is essential to plant safety. All coals oxidise during storage but sub-bituminous coals (such as those from the Powder River Basin) due to their friability and porosity are especially prone to spontaneous combustion.
