ABSTRACT:
The present invention relates to a high capacity movable plant for continuously distributing nitrogen in gaseous phase or in a mixture gaseous and liquid phases for extinguishing fires comprising at least a high capacity thermally insulated tank for storing nitrogen in liquid phase at a temperature of about -196.degree. C. and at maximum pressure of about 405.2 kPa and from which nitrogen in liquid phase is supplied, with a liquid nitrogen supplying capacity of about 50 m.sup.3, to a pumping unit comprising at least three pumps each having each a flow rate of 175 m.sup.3 /h with a maximum differential pressure of 1013 kPa. The liquid nitrogen is vaporized in the vaporization and mixture regulation unit with a vaporization capacity of about 360,000 m.sup.3 /h for liquid nitrogen. The vaporization and mixture regulation unit includes at least a heat exchanger, a wind tunnel, a ventilation assembly, an air inlet window through which the liquid nitrogen is vaporized and the gaseous phase can be mixed with the liquid phase through suitably arranged valves and ejectors. The nitrogen in the gaseous phase or the mixture of nitrogen in the gaseous and liquid phase enters an exhaust duct where the temperature can vary from -100.degree. C. and +20.degree. C. and the pressure can vary from 588 to 1986 KPa. The plant also includes a power station for powering the plant and a control and command unit to command which uses a microprocessor to assure the automatic and sequential operation of the plant.
