Maintenance & Refilling Dry Powder Fire Tank System
Dry Powder Fire Tanks-also known as Dry Chemical Powder (DCP) Fire Extinguishing Systems-are a type of fixed firefighting system used primarily on ships, offshore platforms, and industrial facilities to combat Class B (flammable liquids and gases) and Class C (electrical) fires.
Key Components of a Dry Powder Fire Tank System
Dry Chemical Powder Tank :
-
Typically pressurized or unpressurized tanks holding ABC (monoammonium phosphate) or BC (sodium bicarbonate or potassium bicarbonate) dry chemical powder.
Nitrogen Cylinder :
-
Used to pressurize and propel the powder through the pipework during discharge.
Distribution Piping and Nozzles :
-
Directs the powder to protected zones like cargo decks, pump rooms, or manifold areas.
Manual or Remote Activation System :
-
Enables crew to activate the system locally or from a control room.
Operation
-
Upon activation, nitrogen cylinders release high-pressure gas into the DCP tank.
-
The powder is fluidized and forced through a piping network.
-
Discharge nozzles spread the powder over the fire area, interrupting the chemical reaction of combustion.
Refilling Includes :
-
Emptying and cleaning the tank.
-
Refilling with certified dry powder.
-
Replacing or refilling nitrogen bottles.
-
Leak and pressure testing.
