    • The invention relates to a process for burning waste with simultaneous regeneration of a usable gas and an inert solid residue in which the waste is fed into the upper part of an upright shaft furnace, an oxygen-containing gas is fed into the lower part of the furnace, the organic part of the waste substances is gasified and pyrolyzed, the inorganic part of the waste substances is made flowable, the gas from the upper part of the furnace is taken off and the inorganic material made flowable is taken off at the lower part of the furnace. In order to achieve secondary treatment of the solid and gaseous combustion residues without high expenditure in terms of apparatus, according to the invention the waste is loaded as a charge (3) on a grate (5) provided in the shaft furnace (2), a fuel-oxygen mixture or a fuel-oxygen-air mixture is used as oxygen-containing gas and is introduced into the shaft furnace (2) and oxidized beneath the grate (5), above the grate (5) pure or technical-grade oxygen or air enriched with pure or technical-grade oxygen is injected into the waste charge (3) as oxidizing medium and the waste (3) if appropriate together with combustion residues is burned preferably at temperatures of 1400 to 1600.degree. C. (FIG. 1).
    • 本发明涉及一种燃烧废物的方法,同时再生可用的气体和惰性固体残渣,其中废物被输送到立式竖炉的上部,含氧气体被供给到 炉中,废物的有机部分被气化和热解,废物的无机部分可流动,从炉上部排出的气体被取出,使得可流动的无机材料在下部被分离 的炉子。 为了实现固体和气体燃烧残余物的二次处理,在设备方面没有高的费用,根据本发明,废物作为装料(3)装载在设置在竖炉(2)中的炉排(5)上, 使用燃料 - 氧气混合物或燃料 - 氧 - 空气混合物作为含氧气体,并将其引入竖炉(2)中并且在炉排(5)之下在炉篦(5)上方纯化或工业级 将氧气或富含纯或工业级氧气的空气作为氧化介质注入废料(3),如果合适的话,废物(3)与燃烧残余物一起燃烧,优选在1400至1600℃的温度下燃烧。 1)。
