A device comprising a perforated housing containing therein pellets of a chemical composition which undergoes self-sustaining combustion with generation of a combustion gas and an initiator attached to the housing to ignite the pellets. To prevent breaking of the pellets resulting from their movements in the housing, a hollow and resilient retainer member is placed in the housing such that the initiator is exposed to the interior of the retainer and that the pellets are spaced from the initiator by the retainer and held under a compressive force by the r...
A combustion device comprising: a housing defining therein a combustion chamber; a plurality of pellets of a chemical composition, which undergoes self-sustaining combustion with generation of a combustion gas which may be in the form of flame, disposed in the combustion chamber, the housing having at least one aperture through which the combustion gas jets out of the housing; an initiator for ignition of the pellets attached to the housing so as to be exposed to the combustion chamber; a helical spring placed in the combustion chamber in such an arrange...
