CO Monitoring System Brochure

Coal becomes unstable when its moisture content falls below equilibrium. Coal dust is the most unstable form of coal, because its moisture cannot be retained. When there is a reduction in moisture content, the oxidation process is accelerated generating ignition temperature heat and carbon monoxide (CO). If measures are not taken to monitor this process, spontaneous combustion may occur. This presents a problem in coal storage areas and and dust collection systems.
