A METHOD FOR THE AUTOTHERMAL MANUFACTURE OF FIRED MATERIAL USING A VERTICAL FURNACE

摘要

The present invention relates to a vertical, autothermal furnace characterised in that it comprises a furnace that tapers with the lower part wider than the upper part and having a spherical, elliptical or polygonal cross section, said furnace being replenished with carbon-containing pellets; a pellet filler opening; a discharger; and an air regulator. The present invention further relates to an autothermal method of manufacturing fired material comprising the steps of filling said vertical autothermal furnace with carbon-containing pellets and preheating, and then continuously loading carbon-containing pellets into said preheated pellet-loaded furnace, and continuously discharging said autothermally fired material produced by the autothermal firing of said carbon-containing pellets from the lower part thereof. The method of manufacturing fired material using said furnace has the economic advantage of enabling the autothermal firing of pellets using only the heat generated during firing without additional heating.
