    • A bottom for a fluidized bed conveyor is composed of a plurality of members provided with openings and located in contact with each other so that their points of contact are gas impermeable at least during operation of a fluidized bed. The openings may be formed as circumferentially closed holes and/or as laterally open recesses. The members may laterally abut against each other, or may be provided with interengaging lateral projections. The members may be located so that at cold temperatures small intermediate spaces remain therebetween, which spaces are closed during operation as a result of thermal expansion of the members under the action of high working temperatures. Bracing element or elements may be provided which urge the members toward one another.
    • 用于流化床输送机的底部由设置有开口并且彼此接触定位的多个构件组成,使得它们的接触点至少在流化床的操作期间是不透气的。 开口可以形成为周向闭合的孔和/或形成为侧向敞开的凹部。 构件可以横向抵靠彼此,或者可以设置有相互接合的横向突起。 构件可以被定位成使得在寒冷的温度下保持较小的中间空间,由于构件在高工作温度的作用下的热膨胀,操作期间该空间被封闭。 可以提供支撑元件或元件,其促使构件彼此朝向彼此。

    • A method for the production of acetylene from coal and hydrogen is provided by electric arc heating. The coal has a content of volatile components (i.waf) from about 25 to 44 percent and a content of organic oxygen (i.waf) of less than 9 percent and is ground to a diameter of less than 0.5 mm. The coal is then separated into two to four grain size fractions and one of the grain size fractions is loaded on a hydrogen containing gas. The gas carrying the coal is heated by way of an electric arc with an energy of from about 5 to 20 kJ/l (in normal state). The ratio of electric power employed to coal stream is from about 4,000 to 40,000 kJ/kg coal. The coal is heated for a time duration about inversely proportional to the third root of the specific outer surface of the coal gain fraction. The resulting product gas is quenched with cold liquid hydrocarbons, with hydrogen or water. Acetylene yields of up to about 0.41 kg acetylene per kg coal can be obtained.
    • 通过电弧加热提供从煤和氢生产乙炔的方法。 煤的挥发性组分(i.waf)含量为约25至44%,有机氧含量(i.waf)小于9%,并被研磨成小于0.5mm的直径。 然后将煤分离成两至四个粒度级分,并将一种晶粒尺寸级分装载在含氢气体上。 携带煤的气体通过约5至20kJ / l的能量的电弧加热(在正常状态下)。 煤矿用电量比例约为4000〜40,000千焦/千克煤。 煤被加热一段时间,与煤增益部分的特定外表面的第三根成反比。 所得产物气体用冷液体烃与氢气或水淬灭。 可以获得每公斤煤高达约0.41千克乙炔的乙炔产量。
