A liquefied gas fuel for generating highly luminous colored flame, which can prevent nozzle clogging because of a remarkable reduction in the dissociation and precipitation of inorganic metal salts, can generate stable colored flame without causing intermittent fading, and can give a colored flame originating in each constituent metal far clearer than what has been observed hereinbefore. This fuel is produced by dissolving a color developing agent comprising at least one compound selected from the group consisting of organic metal salt compounds, organic metal chelate compounds, inorganic metal salt compounds and boric acid compounds and a color developing aid comprising a nitrogenous compound in a flammable gas which vaporizes under atmospheric pressure.
一种用于产生高亮度彩色火焰的液化气燃料,由于无机
金属盐的解离和沉淀显著减少,因此可以防止喷嘴堵塞,可以产生稳定的彩色火焰,而不会引起间歇性褪色,并且可以产生源于每种组成
金属的彩色火焰,比以前观察到的要清晰得多。这种燃料是通过将至少一种
显色剂(选自
有机金属盐化合物、有机
金属螯合物、无机
金属盐化合物和
硼酸化合物)和一种显色助剂(选自
含氮化合物)溶解在可燃气体中产生的,该气体在大气压力下蒸发。
