ABSTRACT:
A device for extinguishing oil well fires having an inverted conical steel chamber which is lifted by a crane and placed over the wellhead of a burning oil well. The chamber is dropped into place so that it embeds itself into the sand or soil around the wellhead. Numerous fire hoses supply water to the interior of the chamber to extinguish the fire. Gas exhaust valves vent the interior of the chamber so that the pressure of the steam created does not lift the chamber off of the fire. A remotely controlled damper plate at the top of the chamber can be closed to seal off the fire inside the chamber. The chamber is made in sections that can be dissassembled and nested together for ease in shipping or storage.
