ABSTRACT:
A firefighting installation for floating roof hydrocarbon storage tanks comprises a series of vertical pipes disposed regularly around the tank. A sprayer at the top of each pipe is adapted to form a flat jet of extinguishing foam directed towards the interior of the tank along its inside wall. A pressurized water supply is connected to the pipes through an emulsifying agent feed system. An air injector on each pipe near the sprayer favors the formation of the foam. Each sprayer includes two nozzles set at an angle to each other and directed towards the floating roof. Each nozzle incorporates a longitudinal slot in its end portion opposite the free end and facing towards the floating roof.
