Original Title:
Προσθήκη βαρύτη, κρυολίθου ή φθορίτη στην φαρίνα κλίνκερ με σκοπό την μείωση της θερμοκρασίας έψησης και του αποτυπώματος άνθρακα.
Translated title:
The additional presence of baryte, cryolite, or fluorite to the clinker raw meal in order to reduce the burnability index and the carbon footprint.
Summary:
In the present work, the results of a series of analyzes and experiments are described and evaluated with the aim of reducing the burnability and consequently the supply of fuel to the rotary kiln, for the production of clinker. In order to achieve this goal, the separate addition of 3 minerals, barite, fluorite, or cryolite, in specific percentages to the raw meal, was considered legitimate, in order to reduce the burning temperature (burnability, BI). The work also refers to the air pollutants produced during the combustion process, the pollution phenomena that are related to them as well as the Legislative Frameworks that apply to their reduction. The properties and characteristics of each mineral are analyzed as well as their uses inside and outside the Cement Industry. In order to check their suitability as fluxes, it was necessary to perform BI (Burnability Index) hydrochemical analyzes as well as instrumental measurements through XRD (X-Ray Diffraction Power), XRF (X-Ray Fluorescence), E5 (Epsilon 5). ), TGA (Thermogravimetric Analysis). Then follow the results of the analyzes and their evaluation. The last chapter presents conclusions and proposals, innovative ideas, and innovative technologies, which aim to reduce emissions and consequently the carbon footprint (carbon footprint) that adversely affects the environment and is a major factor of concern for the cement industry.
