Boilers

Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 m (0.001 in). Coal burns in suspension, like the combustion in an oil- or gas-fired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace volume using burners that look somewhat like oil

In fact, to combat this fire hazard, arrangements for mill-inerting systems with inert gases (e.g., N 2 and CO 2) need to be made (another purpose is to reduce air supply). This is more important for ball-and-tube mills, especially when these are operated with one side only
