日本燃料不足,为节约能源,设计了一种新的铝熔炼炉。经实际使用,在节约燃料和减少金属消耗方面效果显著。传统的反射炉完全依赖燃烧产生的幅射热来熔化和过热铝。这种燃烧要求熔池有高的温度和足够大的熔池来达到所要求的热交换,因之,燃烧室温度一般超过1100℃,熔池容积为炉子每小时熔化量的8～10倍。其废热虽然能被利用,但由于熔化金属长期与燃烧产物接触,引起金属氧化,难以得到改善。日本的“喷射熔化炉”(商标为Jet Melter)是一种应用辐射和对流的热交换原理的熔炼炉。它由三个分开的区域组成(见图),即一
Japan’s fuel shortage, in order to save energy, designed a new aluminum smelting furnace. The actual use of fuel saving and reduce metal consumption significant results. The traditional reverberatory relies entirely on the radiant heat generated by combustion to melt and overheat the aluminum. This combustion requires the puddle to have a high temperature and a sufficiently large puddle to achieve the desired heat exchange. Therefore, the temperature of the combustor typically exceeds 1100 ° C and the bath volume is 8 to 10 times the amount of melting per hour of the furnace. Although its waste heat can be used, it is hard to be improved because the molten metal comes into contact with the products of combustion for a long time, causing the metal to be oxidized. Japan’s Jet Melting Furnace (Jet Melter) is a melting furnace that applies the principles of radiation and convection heat exchange. It consists of three separate areas (see figure), ie one
