Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk.
Protecting the coal mill by monitoring CO and O2 SICK
Coal dust is commonly used as a primary fuel for cement kilns. Inert gas is introduced into the coal mill to prevent fires. A rise in the O 2 concentration indicates a leak and the entry of air. By performing continuous O 2 measurement, leaks can be identified early and dealt with in a timely manner. If required, CO measurement can be added to detect smoldering fires.
