Coal dust

Coal dust is a fine powdered form of coal which is created by the crushing grinding or pulverizing of coal Because of the brittle nature of coal coal dust can be created during mining transportation or by mechanically handling coal It is a form of fugitive dust Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier

An unsteady‐state model of a pulverized coal cloud including the submodels of radiation and convection was used to study the ignition characteristics of a Datong bituminous coal under the conditions of O 2 /N 2 and O 2 /CO 2 atmospheres An increase in the ignition temperature was calculated for the bituminous coal when air (21% O 2 + 79% N 2) was replaced with a
