Evaluation of the combustion process in the calcined clay production reactor

• Problem: Energy models for the reactor (rotary kiln) at the LC3 pilot plant have not been developed.
• Objective(s):
To diagnose the reactor (rotary kiln) at the LC3 pilot plant.
To develop energy models for the rotary kiln at the LC3 pilot plant.
To validate the energy models obtained for the rotary kiln at the LC3 pilot plant.
• Methodology: Concepts of thermodynamics and heterogeneous reactors were applied, using spreadsheets and MatLab to solve the generated expressions.
• Results and discussion: Phenomenological models of the rotary reactor for clay calcination were obtained for the combustion stage. The models were validated for three industrial tests carried out at the LC3 cement plant, demonstrating the feasibility of simulating this stage and its potential optimization. Results were obtained from measurements of kcal/kg of calcined clay, and a reduction in polluting gases such as CO2, CO, SO2, among others.
• Conclusions: Models characterizing the combustion and energy balance of the rotary reactor were obtained.
Validation of the phenomenological models of the rotary reactor.
Measurements characterizing these processes were obtained, kcal/kg of calcined clay.
