Abstract:
1. The method of extinguishing a fire by the flames containment and suppression process herein described which comprises the steps of: A) compressing a continuous mass gas mixture of dry air and superheated water vapor in a fire location; B) receiving an external fire-fighting agent of at least one of liquid, foam, powder, granular, or gaseous which is delivered to the fire location; C) storing the external fire-fighting agent at the fire location; D) supplying a continuous mass flow of the gas mixture of dry air and superheated water vapor to the flames site; E) supplying a continuous mass flow of the external fire-fighting agent of at least one of liquid, foam, powder, granular, or gaseous to the flames site; F) expanding in a jacketed or thermally insulated flow passage the continuous mass flow of the gas mixture of dry air and superheated water vapor, increasing the flow velocity, and thereby, generating a high flame-front penetration and blast capability, flames-suppression air jet, which is directed to the flames site disrupting said flames natural aerodynamics and blasting their origin, bringing about such flames blown off and combustion process extinction; G) expanding in a horizontal or angled flow passage or passages the continuous mass flow of the gas mixture of dry air and superheated water vapor, increasing flow velocity, and thereby, generating a directional flame-containment air jet or jets, which are directed to the flames site, constraining run-away flames fronts from escaping, and preventing non burning surrounding materials inflammation; H) expanding in a outer jacket or flow passage of the continuous mass flow of the gas mixture of dry air and superheated water vapor, increasing the flow velocity, and thereby, establishing a heat shield or thermal insulation air mass flow, in which the discharge air jet is directed to the flames site, preventing thereat, the heat transfer from the high temperature surrounding flames environment to the expanding continuous flow of ambient air in said jacketed flow passage and to the flames-suppression air jet; I) expanding in the jacketed or thermally insulated flow passage, the continuous mass flow of the gas mixture of dry air and superheated water vapor, increasing the flow velocity, preventing the heat transfer from the high temperature surrounding flames environment, decreasing the flow temperature, and thereby, establishing a condensation shock wave, which produces water droplets from the superheated water vapor contents in said continuous compressed ambient air mass flow, generating thereat, a flames-suppression air jet with water droplets, which are directed to the flames site, wetting and cooling the inflammable materials, provoking further combustion inhibition; J) feeding in the continuous mass flow of the gas mixture of dry air and superheated water vapor that expanding in the jacketed or thermally insulated flow passage, a continuous flow of the external liquid or foam fire-fighting agent, stored in a tank at the fire location and transported to the flames site by mean of a air pressurized tank discharge, and thereby, establishing its aspersion on the flames by means of said continuous mass flow of the gas mixture of dry air and superheated water vapor, generating thereat, a flames-suppression air jet with the external liquid or foam fire-fighting agent, which are directed to the flames site, extinguishing such flames; K) feeding in the continuous mass flow of the gas mixture of dry air and superheated water vapor that expanding in the jacketed or thermally insulated flow passage, a continuous flow of an external powder or granular fire-fighting agent, stored at the fire location in a silo and transported to the flames site by means of a pneumatic conveyor discharge, and thereby, establishing its aspersion on the flames by means of said continuous mass flow of the gas mixture of dry air and superheated water vapor, generating thereat, a flames-suppression air jet with the external powder or granular fire-fighting agent, which are directed to the flames site, extinguishing such flames; L) feeding in the continuous mass flow of the gas mixture of dry air and superheated water vapor expanding in the jacketed or thermally insulated flow passage, a continuous flow of an external gaseous fire-fighting agent, stored at the fire location in a tank and transported to the flames site by means of a dry air or gaseous agent pressurized tank discharge, and thereby, establishing its aspersion on the flames by means of said continuous mass flow of the gas mixture of dry air and superheated water vapor, generating thereat, a flames suppression air jet with the external gaseous fire-fighting agent, which are directed to the flames site, extinguishing such flames;
