The coal mill is operated as an air-swept mill and “blows” directly into the combustion zone of the steam boiler, via a pipeline connection. In case of an explosion, normally as consequence of ignition within the mill chamber, there will be explosion propagation towards the boiler. The combustion “cloud” will propagate to where it finds.
The explosion characteristics are shown in Table 1. The ignition energy of the coal powder is 50mJ, so electrostatic and mechanic sparks should be considered as ignition sources. The explosion index K max is less than 10 MPa.m s, so venting and suppression are effective for the coal powder. Table 1 Explosion characteristics of the coal powder.
