Abstract
A system, for extinguishing flames from combustible fluids exiting from a pipe, has an elongated tubular extinguisher body being disposable over the fluid emitting pipe, the extinguisher body having a lower inlet end and an upper outlet end and the body being adapted to accommodate a flow of the combustible fluid through the extinguisher body. A valve arrangement is mounted in the extinguisher body adjacent its upper outlet end for gradually limiting and finally eliminating the flow of the combustible fluid through the extinguisher body. Also, a flame inhibiting structure, including circular nozzle structures, are disposed adjacent the lower inlet end of the body and adjacent the valve arrangement and externally of the extinguisher body for preventing the support of combustion of combustible fluids adjacent the circular nozzle structures.
