    • A method of making a fuel for a portable heater comprises heating a salt of iron with a carboxylic acid at a temperature from about 400oC to about 700oC under an inert or reducing atmosphere to produce a composite material comprising carbon and iron nanoparticles. The fuel may be mounted to a substrate, such as a mesh or foil, and incorporated into a self-heating packaging. Typically, the packaging comprises a wall defining a chamber that, in use, contains a substance to be heated, e.g. a foodstuff or liquid. A heating manifold in thermal communication with the chamber contains the fuel in the inert atmosphere to initially inhibit production of heat otherwise arising from substantial oxidation of substantially all the fuel in the manifold in an exothermic reaction. A vent in the manifold is initially sealed and air-tight, but selectively opening of the vent allows oxidation of the iron nanoparticles. The chamber is then heated by the transfer of heat from the fuel to the chamber, the transfer of heat being by at least one of direct thermal conduction through the wall, thermal convection or indirect thermal heating arising from heating of a fluid medium that is introduced into the chamber.
    • 制造用于便携式加热器的燃料的方法包括在惰性或还原气氛下,在约400℃至约700℃的温度下用羧酸加热铁盐,以制备包含碳和铁纳米颗粒的复合材料。 燃料可以安装到诸如网或箔的基底上,并且被并入自加热包装中。 通常,包装包括限定室的壁,其在使用中包含待加热物质,例如, 食物或液体。 与腔室热连通的加热歧管在惰性气氛中包含燃料,以最初抑制热量的产生,否则由于在放热反应中基本上全部燃料在歧管中的基本氧化。 歧管中的通风口最初是密封的并且是气密的,但选择性地打开通气孔可以使铁纳米颗粒氧化。 然后通过将热量从燃料传递到室来加热室,通过壁的直接导热中的至少一种传递热量,由引入的流体介质的加热产生的热对流或间接热加热 进入房间
