    摘要: The oxygen generating compositions contain carbon-free metal powder as fuel to minimize generation of carbon monoxide. The carbon-free metal powder can be selected from copper, zinc, and antimony, and mixtures thereof, and can be used in combination with tin or iron. The oxygen generating compositions produce a breathable gas upon ignition of the composition, and comprise about 1-15% by dry weight of the metal powder as a fuel; about 0.1-5% by dry weight of at least one alkaline compound; a transition metal oxide catalyst; and the remainder substantially comprising an oxygen source. The oxygen generating compositions can optionally include a binder. An oxygen generating candle can also have an ignition pellet having a composition of about 25-50% by weight copper, zinc or antimony, 5-20% by weight Co.sub.3 O.sub.4, about 2-5% by weight glass powder, 0-25% by weight KClO.sub.4, and the balance being substantially NaClO.sub.3.

    摘要: A chemical oxygen generator includes multiple parallel sequentially connected chemical core sections that extend the duration of operation of the chemical oxygen generator. An end of a first core section is contiguous with a chemical core high reactivity section, and a thermal insulation layer is disposed between an end of a second core section and the chemical core ignition plate, as well as between the bodies of the first and second core sections. A chemical core transition section is disposed between the other end of the first core section and the second core section, to insure that the reaction front propagates properly.

    摘要: An improved chemical oxygen generator (10) includes an oxygen generating candle (12) having an oxygen source, which upon decomposition will yield oxygen, and a nontoxic additive to smooth decomposition and suppress formation of toxic free chlorine gas. The nontoxic additive may be taken from the group consisting of: (1) the oxides, hydroxides and carbonates of calcium and the rare earth elements; (2) the hydroxides and carbonates of magnesium; and (3) mixtures of the foregoing. A complete chemical oxygen generator utilizes the candle (12) of the invention. The oxygen generator preferably includes a canister (14), oxygen-generating candle (12), and an ignition device (16). Triggering of the ignition device ignites an ignition pellet (52) which initiates decomposition of the candle body (50). Once initiated, the candle will sustain decomposition to release breathable oxygen until the candle is completely reacted.
