Method for extinguishing burning oil well - involving prodn. of fire wall and use of guided introduction of fluid inert gas into centre of fire and withdrawal of oxygen@ from air

摘要

Appts. is used to produce a fire wall surrounding the burning oil source. The combustible material for the wall can be gas-form or liq., and is applied with pressure. Varying local conditions of burning oil sources can require several ring-shaped devices of varying dias. at various heights. Also used is a device for the targeted introduction of a fluid inert gas into the centre of the fire, e.g. in the form of a rollable and extendable pipe conduit. The fire wall causes a withdrawal of air oxygen required for the oil to burn, thereby extinguishing the flame. The liq. inert gas adheres to surfaces in the region of the extinguished flame, thereby having a cooling effect and preventing a recurrence of the fire.
