The clinker manufacturing process starts with the extraction of the raw meal from the homogenization silo to insure that the raw meal is stable and homogenized in order to produce consistent clinker quality. The preheating of the material takes place in pre-heater cyclones fitted with a pre-calciner fired with petroleum, natural gas or coal.
A 15% of fuel substitution can represent a reduction of 51 t per day of CO 2 emission for a daily production of 4100 t of clinker (actual production of L6 line), while for the same amount of raw material substitution the daily reduction is 10 t of CO 2. This fact confirms that the amount of substitution ratio is significant in the case of fuel ...
