| 摘要 |
The invention relates to a vertical-shaft kiln (2) for producing a clinker comprising a tubular enclosure (4) comprising, from top to bottom: a feeding section (14); a decarbonatation section (16) having an inclined inner surface (16a); a clinkerisation section (18) having an inclined inner surface (18a); a first collection section (20); first extraction means (42) arranged in such a way as to extract the clinker from the first collection section (20); means for generating a first gas having a temperature of between 950°C and 1250°C, and for feeding same into the decarbonatation section (16); means for generating a second oxidising gas having a temperature of between 1250°C and 1450°C, and for feeding same into the clinkerisation section (18); and first means for the intake of the first and second gases from the feeding section (14). |
