PULVERIZER MILL PROTECTION SYSTEM

摘要

A system for suppressing and inhibiting fires in coal pulverizer mills can include a fire suppression solution storage tank, a flow control cabinet, an equipment control/pumping enclosure, an air distribution system, and injection piping and nozzles installed at various positions in one or more pulverizer mills. A first set of nozzle assemblies in communication with the fire suppression solution can be positioned in the mill to disperse the suppression solution within the classifier zone of the mill. A second set of nozzle assemblies in communication with the suppression solution can be positioned within the mill to disperse the suppression solution within the grinding zone. A third set of nozzle assemblies can be positioned within the primary air duct of the mill.
