Coal Storage

Coal is typically powdered for use in heating the rotary kiln burning zone. Prior to milling, it must be stored, which is a fire risk. Continuous, automated monitoring is necessary to detect any hot spots in the stored coal pile, but the size of the pile presents challenges to this monitoring.

Coal reacts with air to form carbon monoxide and carbon dioxide, in an exothermic reaction which can create hot spots. This can lead to fires, so it is important to identify hot spots early, to ensure personnel safety, prevent plant damage and avoid loss of coal stock.

This safety monitoring helps stop fires taking hold, which in turn protects staff and equipment from harm. As fires can consume coal stocks and cause expensive process shutdowns, it also provides cost benefits to the process.
