OPTIMISED VERTICAL-SHAFT KILN FOR PRODUCING SULFOALUMINOUS CLINKER

摘要

the invention relates to a furnace (2) for the production of a cement clinker, comprising: a tubular chamber (4) with a section from top to bottom: food (14). a portion of the shell (16) having a lower inclined surface (16a). a section of the sintering (18) with a sloping lower surface (18a).a first section (20); collection of early extraction means (42) arranged to extract the clinker of the first portion of the collection means (20), a first gas generation level and having a temperature of 1250 c,and brought it into the section of the shell (16); a second means for generation of the oxidizing gas with a temperature of 1250 c and 1450u00b0c, and brought it into the burning portion (18), and first means for suction first and the second gas from the supply section (14).
