The known method for processing of industrial & military poisonous substances and chemicals provides for heating of the said poisonous substances in the presence of a gaseous oxidizer and non-organic additives entering into a chemical interaction with a treating product, and consequent removal of the reaction products. In the newly developed method, substances are simultaneously treated with a gaseous oxidizer (air and diluting fuel) in the working area of the process activation installation. Destruction is effected through flameless combustion with addition of a liquid or gas fuel outside the activation installation in a specially designed cooling combustor. The air is fed in two flows: the first air flow is directed in the amount of 5-20% of the theoretically required oxygen, together with a utilizing substance and additives; the second air flow is directed into a mixing chamber of a nozzle which is an integral part of the working zone of the installation, located at its outlet.

In the second modification of the new method, calcium hydroxide water suspension together with all additives and the main substance is delivered into the working zone of the first installation to bind fluorine to produce calcium fluoride.

In the third modification of the new method, solid combustion products are differentially separated out of the gas phase through a staged cooling. Fluorine compounds are settled in the form of calcium fluoride powder at a temperature of below 1400° C in an individual chiller. Phosphor compounds and arsenic are removed at temperatures of 250-350° C through their precipitation in the form of amorphous vitreous mass on the working surface of an individual separator, heated to the temperature not less than 310° C. The said separator is installed downflow the chiller. Compounds of chlorine, sulfur and remains of fluorine and arsenic are withdrawn by wet removal methods in the working zone of the second process activation installation located downflow the said separator which retains a major part of phosphor and arsenic amount thorough the dissolution of the said compounds in a calcium hydroxide water-based suspension. Captured solid particles are then precipitated and isolated. Chlorine compounds remain in the solution.

In the fourth modification of the new method, an additional fuel in the amount of 15-25 % (by weight) is added.

In the fifth modification of the new method, on the contrary to the 3^rd modification in which separation and destruction of a vitreous mass consisted of phosphor and arsenic compounds is effected through periodical and rapid cooling of the separator working surface down to temperatures of 100-150° C and consequent heating to the temperatures of not less than 310° C.
