日本的高炉烟尘新处理法是利用废气的热能回收烟尘中的锌。烟气和空气(温度达900—1300℃)沿自动操纵线路引入燃烧室。锌氧化物在燃烧室内通过焦炭层时发生还原,并以蒸汽形态随同烟气一起进入集尘室,在集尘室内清除掉烟气中的粗粒 FeO、
Japan’s new blast furnace dust treatment is the use of waste heat recovery of soot in the zinc. Flue gas and air (temperatures up to 900-1300 ° C) are introduced into the combustion chamber along automatic lines. Zinc oxide in the combustion chamber through the coke layer occurs when the reduction and in the form of steam along with the flue gas into the dust chamber in the dust chamber to remove the flue gas in the coarse FeO,
