Advantages Water Spray System

Advantages Water Spray System. Entire area is flooded with water, hence very useful fore fire fighting in hazardous area, conveyor, storage tanks, etc. where manual approach is difficult. Very quick in response. The fire losses is kept low as the area adjacent to fire also get water protection and so chances of spreading fire is negligible.

Fire and Explosion Hazards in Cement Manufacturing

Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk.

Hazardous Area Classifications

An industrial area is considered a hazardous area when it contains three fundamental components: A flammable substance (which can be a gas, liquid, or solid), an oxidizer, and a source of ignition. The flammable substance can be anything from gasses and liquids such as hydrogen, gasoline and kerosene, to solid particulate such as dust or small fibers.
