在苏联的耶纳基耶沃烧结厂,已设计和应用一种长点火器,用间接辐射加热法对烧结矿表面层进行保温处理。结果,改善了气体燃料的燃烧状况,提高了点火器的热效率。因而混和料的点火效果比较好,烧结矿合格率提高5.64%(绝对值),固体燃料的消耗降低2公斤/吨烧结矿,同时烧结矿强度也有所提高。 At the Yanacoyvo sintering plant in the Soviet Union, a long igniter has been designed and applied to insulate the sinter surface layer with indirect radiant heating. As a result, the combustion of the gaseous fuel is improved and the thermal efficiency of the igniter is improved. Therefore, the ignition effect of the mixture is better, the passing rate of sinter increases by 5.64% (absolute value), the consumption of solid fuel decreases by 2 kg / t sinter, and the strength of sinter also increases.
