In this paper, an architecture based on a two-layer linear MPC strategy is designed for the clinker production phase control and optimization. The approach described in [ 7] is further detailed and extended. In particular, through a cross-fertilization procedure, the approach proposed in [ 8] is suitably customized for the process at issue.

Il est le composant de base pour la production de ciment. Les matières premières pour la production de minéraux de clinker contenant: oxyde de calcium (CaO), généralement obtenu à partir de calcaire, oxyde de silicium (SiO) l'oxyde d'aluminium (Al) oxyde de fer (Fe) et l'oxyde de magnésium (MgO). L'extraction du minéral se produit dans ...

Reducing the amount of CO 2 released during cement production is one of the main challenges for reaching net zero by 2050. With most cement-related emissions originating from the clinker production process, changing the conventional manufacturing process and raw materials used will be crucial. For many years, several strategies have …

Clinker Production. In modern cement plants, the burning process is performed in a chain of three systems. In the multistage cyclone preheater with calciner, the raw meal is preheated to about 800 to 900 ° C and decarbonated by kiln exhaust gases. In the rotary kiln itself, a temperature of approx. 1450 ° C causes sintering – a chemical ...

Global cement production has reached 3.9 billion tons. However, the clinkerization process, which is the basis of cement production, is responsible for an approximate annual global CO2 emission of 2 billion tons. As part of CEMBUREAU's 5C strategy, the European cement industry aims to achieve carbon neutrality throughout the cement-concrete value chain …

La materia prima, durante su calcinación, sufre reacciones químicas formándose granos duros, del tamaño de una nuez, de un nuevo material llamado Clinker. El Clinker que se forma sale del horno a esta temperatura, y entra dentro del enfriador donde es enfriado hasta una temperatura de 80°C en enfriadores de parrillas ("Viacha") o ...

The main factors affecting clinker reactivity and PSD. Clinker mineralogy and nodule size depend largely on the feed composition and the amount, distribution and nature of the melt phase formed in the burning zone. The clinker melt promotes the reaction between belite (C 2 S) and free lime to form alite (C 3 S), so it is critical for clinker ...

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 ...
