May 10, 2013 Pulverized coal injection (PCI) is a process which involves injecting large volumes of fine coal particles into the raceway of the blast furnace (BF). Pulverized coal is an important auxiliary fuel used in the BF ironmaking. PCI provides auxiliary fuel for partial coke replacement and has proven both economically and environmentally favourable.
Abstract. Reports of 26 coal pulverizer fires and explosions are reviewed in order to elucidate causes and preventive measures. Most of the explosions occurred during pulverizer shutdowns or restarts. The most common ignition scenario involved coal dust accumulations in the mill spontaneously igniting and coming in contact with a flammable coal.
Coal pulverizer mill fires and explosions present a major safety and financial concern for owners and operators of coal fired boilers and utilities. Such incidents can damage or completely destroy the mill and ancillary equipment. Workers in the vicinity of the mill may be injured or killed by thermal injury, hot gases and or flying debris.

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.
