  • Wellhead fire extinguisher and method extinguishing a well fire
    Patent number: 5154234
    Abstract: A wellhead fire extinguishing apparatus comprises a flame containment housing which is lowered into place above the wellhead fire to create a chimney-like updraft and draw the fire surrounding the wellhead into the housing. The housing is then lowered to the well platform or ground and the flame is cooled by a coolant/flame retardant to cause the ignition point of the flame to rise above a flapper valve in the housing. The flapper valve is closed by remote actuation to separate the flame from the fuel flowing from the wellhead. The unburned fuel is vented from the housing and the flame is extinguished by the coolant/flame retardant.
