Abstract:
A fire fighting device having a funnel shaped jacket that attaches to a rib framing system that is strapped around a bulk storage tank, the ribs attached to a relief channel located at the base of the tank, the jacket is held away from the tank shell by the ribs, the void created between the funnel jacket and tank shell is the waterway, fire stream cooling water is collected at the top of the tank by the funnel, the water is then gravity fed through the waterway, the flow rate of the water is controlled by the size of the relief ports located in the relief channel. As the water travels across the face of the tank within the waterway, it absorbs the heat radiated into the tank by an outside heat source. The heat transferred water enters the relief channel through inlet ports. The heated water is then released outside the waterway system through relief ports.
