AI Kiln Solution For Optimized Control Siemens
The basic process in a cement production plant is burning a mixture of raw material containing Carbonates and Silicates in a kiln to produce solid oxides, clinker, which is then cooled and milled to make the cement dust. Fig. 1 shows the structure of a rotary kiln with the most important variables used for control purposes in a simplified way [3].The primary use of fossil fuels in cement production occurs during pyro-processing. CO 2 emissions during this process depends on the type of production process and its efficiency and also on the type of fuel used in the pyro process. The role of the percentage of additives used and the clinker-to-cement ratio also play significant roles.An overview of alternative raw materials used in cement and clinker

Clinkerization an overview ScienceDirect Topics
Cement production is a highly energy-intensive process. Cement making consists of three major process steps: raw material preparation, clinker making in the kiln, and cement making. Raw material preparation and cement making are the main electricity-consuming processes, whereas the clinker kiln uses nearly all of the fuel in a typical cement plant.grinding of raw materials, clinker production, grinding of clinker and packing to determine the energy use. Based on life-cycle analysis using input–output transaction tables, the energy use for cement production is found to be 4.67–8.05 MJ/kg [19]. Fonta et al.

Chemical exergy influence in the exergetic analysis of a real clinker
The most energy demanding process in the cement industry is clinker production, carried out in a rotary kiln. Thus, rotary kiln energetic and exergetic analyses are useful tools to reach cement production process improvements. Energetic analysis is based on the first law of thermodynamics and allows one to calculate the heat uses and losses. The basic function of this process is to improve the reaction efficiency of cement clinker production. Besides the main production processes of cement clinker, the system boundary of this study also includes an important indirect subsystem, i.e., the subsystem of energy supplying, which includes power generation sector and coal miningExergy-based resource consumption analysis of cement clinker production
