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 communiion with the fire suppression ...
Coal Mill
In fact, to combat this fire hazard, arrangements for millinerting systems with inert gases (, N 2 and CO 2) need to be made (another purpose is to reduce air supply). This is more important for ballandtube mills, especially when these are operated with one side only. Therefore, CAD comes into operation whenever there is need to bring down the mill temperature. Naturally when this ...

Coal Bunker Fire Extinguishing System
The principle of this protection is to push CO2 vapour through the coal, reach the level of absorption, and fill all the void spaces between the coal particlestoreduce the oxygen available to the fire to near zero. Holding this condition long enough will effect fire extinguishment. To inert the coal, CO2 vapours used. CO2 injected in to the bottom of the bunker has been reported effective in ...
COAL HANDLING SAFETY
the mill is restarted. The Millwatch system is installed near the classifier and can detect the CO emitted from any hot inclusions within the residual coal. With many baseload plants now being frequently dispatched, the risk of a astrophic event mounts. HIGH RISK AT MILL STARTUP AND SHUTDOWN Several methods are available to detect the presence of oxidation within the mill or silo ...

Operate at system primary air temperatures below those historically used as normal. The trend is toward classifier outlet temperatures of 125 OF away from 150 160 OF. In addition to the above, some utilities have utilized what has been termed "inerting systems.
PULVERIZER MILL PROTECTION SYSTEM
One embodiment of the invention comprises a fire suppression, cooling and mill inerting system that inhibits coal pulverizer mill fires, explosions and/or puffs, as well as control vaporous combustible gases emitted from the coal inside an idle mill. The system injects a fire suppression solution as a mist through multiple nozzles loed at various points in the coal mill/pulverizer. The fire ...

Inerting system
An inerting system decreases the probability of combustion of flammable materials stored in a confined space. The most common such system is a fuel tank containing a combustable liquid, such as gasoline, diesel fuel, aviation fuel, jet fuel, or rocket being fully filled, and during use, there is a space above the fuel, called the ullage, that contains evaporated fuel mixed ...
