Fire and Explosion Prevention in Coal Pulverizing Systems

point of combustion. In the air-conveyed direct-fired coal pulverizing system, used extensively in the industry today, there normally exists a combustible coal/ air mixture in the burner lines and pulverizer equipment. Hence there is the continual danger of fires and, under certain conditions, explosions.

Coal Pulverization System: Explosion Prevention and

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
