Abstract:
An improved fire-fighting system for dispensing a quenching agent on a fire source, the fire-fighting system comprising:a solid mounting structure; at least three boom sections connected together in an articulated arrangement, one of the at least three boom sections rotatably coupled to the solid mounting structure; conveying pipeline means for delivering the quenching agent at a throughput of at least about 3,000 gallons per minute, the conveying pipeline means including a conveying pipeline being formed of solid-walled pipe sections having an inside diameter of at least about six inches and being coupled to and articulable with the at least three boom sections; a nozzle connected to a distal end of the conveying pipeline; and pump means for pumping the quenching agent under pressure through the conveying pipeline means to the nozzle at a turbulent flow rate of at least about 3,000 gallons per minute when a pump discharge pressure is 150 pounds per square inch, the pump means including a pump supported by the solid mounting structure and coupled between a source of the quenching agent and a proximal end of the conveying pipeline.
