APPARATUS AND METHOD FOR RAPIDITY DISTILLATION OF COAL USED SPOUTED BED

摘要

Coal dry distillation method is provided, and this method supplies heating air to the spouting layer which is dry from hot air at the initial stage of dry distillation, and stops supplying the heating air when the temperature inside the spouting layer reaches a certain temperature, and supplies only room temperature air. The heat generated by burning volatile constituents in coal is used for coal drying.;At this time, by controlling the amount of volatile components of the raw coal and the amount of supply air to control the internal temperature of the ejection bed and the temperature of the coal gas discharged.;Since the ejection layer used here can use coarse raw coal, not only problems such as coal particles being entangled during dry distillation using the conventional fluidized bed, but also the char of the distillation product by adjusting the temperature of the exhaust gas It can also be used for coking coal heating in the production of molded coke using
