Definitions
- the present invention relates to a process for producing heat-generating counter-measures which are intended to be dispensed from sea-based, land-based or air-based systems, with heat being generated when an iron compound reacts with oxygen, thereby forming iron oxide.
- the invention also relates to a pack containing heat- generating counter-measures, which pack comprises a container with a lid and is intended to be dispensed from sea-based, land-based or air-based systems, with heat being generated when the pack is opened, during the dispensing, such that the content of the pack, in the form of an iron compound, makes contact, and is allowed to react, with oxygen, thereby forming iron oxide and heat.
- the object of the invention is achieved by means of a process which is characterized in that the iron compound which is to react with oxygen consists of iron sulphide and by means of a pack which is characterized in that the content of the pack, which content reacts with oxygen, chiefly consists of iron sulphide.
- the iron sulphide can be synthesized inside the pack and, after the pack has been opened, reacts in an attractive manner with the oxygen in the air, thereby forming heat having an appropriate IR signature.
- the reaction between the iron sulphide and the oxygen is guided to at least partially follow one of the reactions shown below or a combination of these reactions: 4FeS + 30 2 -» 2Fe 2 0 3 + 4S + heat 4FeS + 70 2 -> 2Fe 2 0 3 + 4S0 2 + heat.
- the degree of pyrophorous activity i.e. the total energy and the time required to reach maximum temperature
- the degree of pyrophorous activity can be regulated by controlling the supply/ flow of hydrogen sulphide and the temperature at which, and the exposure time over which, the conversion from iron oxide to iron sulphide takes place. Additional regulation can be effected by storing the completed product, when some of the sulphur which remains subsequently reacts and increases still further the degree of the pyrophorous effect possessed by the material.

Abstract
L'invention concerne un procédé de mise en oeuvre de processus produisant de la chaleur, pouvant être mis en oeuvre par des systèmes marins, terrestres ou aériens, la chaleur étant produite lorsqu'un composé de fer réagit avec de l'oxygène de manière à former un oxyde de fer. L'invention concerne également un ensemble (1) faisant intervenir des processus produisant de la chaleur (8). Ledit ensemble comporte un contenant (2) et un couvercle (3) et peut être mis en oeuvre par des systèmes marins, terrestres ou aériens. La chaleur est produite lorsque l'ensemble (1) est ouvert, de telle manière que le composé de fer contenu dans l'ensemble réagisse avec de l'oxygène afin de former de l'oxyde de fer et de la chaleur. Selon l'invention, le composé de fer est composé de sulfure de fer. Le procédé selon l'invention permet de simplifier le processus de production de chaleur, de s'affranchir de chambres à vide ou de zones particulières contenant une atmosphère protectrice, et de mettre en oeuvre des ensembles efficaces.
