APPLICATION aerosol fire-extinguishing compound to prevent gas explosions DUST AND OTHER mixtures with air

摘要

1. A method for applying fire-extinguishing aerosol composition for preventing gas explosions and other dust-air mixtures, comprising a deletion beginning of combustion processes and subsequent explosion, characterized in that to prevent possible explosion impact on the explosive mixture of gases directed velocity jet of fire-extinguishing aerosol that is formed e.g. , in the generator-ignition of at least one solid, liquid or gelled aerosol composition comprising in its composition fuel oxides divisor, catalyst and / or a cooler; and fed into the gas zone, e.g., by pipeline, the fire extinguishing aerosol is guided so that it quickly penetrates into the gas zone, it is mixed with it and surrounds it, except the contact with possible hearth arcing, burning and smoldering, while putting deflates, mixing and inhibitory effect of precluding the possible spread of the front deck fire, leading to combustion and explosion of gas; wherein the composition is applied or a different composition or mixtures thereof, e.g., as separate charges or in admixture with the fire-extinguishing powders or water. ! 2. A method according to claim 1, characterized in that the aerosol composition as fuel contains chemical compounds taken from the group of metals, hydrides and / or metal azides in amounts of from 0.2 to 20 wt.%; alcohols, glycols, acetates, nitrates and / or nitrites and / or azides organic compounds, heterocyclic compounds, esters, rubbers, polyesters, resins, and their mixtures, their solutions and mixtures with water, solvents or solvent mixtures, their solutions, including including condensed polymers on
