ABSTRACT:
A fire extinguishing system for use especially on a floating roof tank includes an enclosure secured to the tank roof. The enclosure carries an agent tank, an expellant tank and an accumulator tank. The agent tank contains fire extinguishing agent. The expellant tank contains pressurized expellant fluid. An expellant conduit extends from the expellant tank to an inlet of the agent tank. A sprayer duct is connected to an outlet of the agent tank and is arranged along one protected zone of the roof rim. A control valve is disposed in the expellant conduit. A heat sensitive pilot conduit is disposed along the protected zone and fluidly connects the expellant conduit with the control valve so that pressure from the expellant tank maintains the control valve closed. If the pilot conduit ruptures, agent is discharged. A bypass conduit connects the expellant conduit with the sprayer duct. Valve mechanism is provided for blocking passage of expellant fluid into the agent tank and for admitting passage of expellant fluid through the bypass conduit, enabling expellant fluid to be discharged from the sprayer duct during testing of the system. A plurality of mounting legs extend horizontally from the enclosure and along the tank roof and are secured to the tank roof. At least one of the legs includes an internal passage which receives the pilot conduit.
