FIELD: fire safety.
SUBSTANCE: method of inerting for prevention and/or extinguishing fire, in which the oxygen content determined in advance is less, the method comprises the following steps: obtaining the initial gas mixture comprising oxygen, nitrogen, and optionally other components in a mixing chamber, preferably in a mixing chamber made in the form of a mixing tube; using the gas separation system at least a portion of the oxygen is separated from this initial gas mixture obtained; and the gas mixture enriched in nitrogen is fed through pipes to the atmosphere of the enclosed space, a portion of the ambient air contained in the enclosed space is extracted from the space, preferably in a controlled manner and fed into the mixing chamber, and the extracted part of the space air is mixed with fresh air, preferably in a controlled manner through the vent mechanism provided in the system of fresh air supply duct connected to the mixing chamber. The inerting system for setting and/or maintenance of pre-determined oxygen content in the atmosphere of the enclosed space, which is reduced compared to natural ambient air. The inerting system comprises a gas separation system that separates at least part of the oxygen from the initial gas mixture, and at that the inerting system comprises a system of supply pipe line for supplying the gas mixture enriched in nitrogen into the enclosed space. A mixing chamber is additionally provided, preferably a mixing chamber made in the form of a mixing tube for obtaining the initial gas mixture. The first pipeline system through which a part of the air contained in the enclosed space opens into the mixing chamber, and at that the second system through which fresh air is supplied into the mixing chamber opens into the said mixing chamber. The group of inventions also relates to the system of integration.
EFFECT: reduction of risk of fire breaking-out, and extinguishing fire in the protected space.
