DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The invention relates to a method of deflagrating explosives, wherein the explosives are burnt up in a deflagration reactor and the flue gases resulting during deflagration are mixed with fresh air fed into the deflagration reactor, thereby being cooled, and then are discharged from the deflagration reactor.
The invention also relates to an installation for the deflagration of explosives, comprising a deflagration reactor in which the explosives are burnt up, the flue gases resulting during deflagration are mixed with fresh air fed into the deflagration reactor, thereby being cooled, and then are discharged from the deflagration reactor through exhaust gas pipes.
Methods as well as installations of that kind are known. They serve for the disposal of articles containing substances which are liable to explode or explodable, such as ammunition, rockets, pyrotechnic sets, and the like, especially from the military field. The reasons for disposal either are that the articles mentioned have reached a certain age from which on the defined characteristics assured upon manufacture of the substances which are liable to explode or explodable and required for their use can no longer be guaranteed or because, for example, weapons systems have been developed further and the ammunition already produced and on stock for those weapons systems can no longer be applied for their destined use. However, also the disposal of the so-called residual contamination or legacy has gained in importance particularly most recently with the generally grown consciousness of the existence of environmental problems. Whereas until some forty years ago the ammunition unused or captured during a war, for instance, was either buried in the ground or dumped at sea there is an awareness now, at least in the industrialized world, of the long-term damage done to the environment by such measures.
The substances liable to explode or explodable mentioned above will be designated hereinafter by the term "explosives". That is generally understood to be solid, liquid, or gelatinous substances and mixtures of substances produced for purposes of detonating or propelling. However, in the instant case also substances which have not been made for the purpose of detonation or shooting also are combined under the term of explosives, such as organic peroxides as catalysts, gas release agents of present day foam and plastics engineering, some pesticides, and many others. Likewise included, for instance, is the well known mixture "thermite" which is understood as being mixtures of aluminum and iron oxide which react while developing a large amount of heat, forming aluminum oxide and iron. This development of heat is utilized for example for welding rails.
Explosives can be available as bulk material of any particle size, as adhesions, in the form of bodies having defined dimensions (e.g. pressed objects), or as a filler in hollow bodies. The list given by Rudolf Meyer in "Explosivstoffe", 6th edition, page 127 et seqq. may serve as an indication of the groups of substances to be understood by the term "explosives".
The disposal of explosives is realized worldwide by the so-called deflagration or detonation of these substances due to the lack of safety involved in their handling, both for the persons and the surrounding material. It is called "deflagration" because practically all explosives which are present in larger amounts continue to react upon initiation of the chemical decomposition reactions without the addition of another reactant, especially without the atmospheric oxygen which otherwise is customary in "combustion".
While the deflagration of explosives up to the present time predominantly still is carried out in the open, with assurance of the necessary personal safety but without any regard for the reduction of emissions of the gaseous reaction products resulting from the deflagration, most recently semi-closed or closed installations and methods connected with them have become known for the deflagration of explosives, inclu
