HERNANDEZ, Ómar Darío; QUIROZ, John Antonio  and  ORTIZ VALENCIA, Paula Andrea. Combustion System Model of a Wet Process Clinker Kiln. Ing. Univ. [online]. 2014, vol.18, n.2, pp.329-353. ISSN 0123-2126.  https://doi.org/10.11144/Javeriana.IYU18-2.csmw.

This paper presents the model of the combustion process of a clinker kiln, which is obtained from an energy balance represented in the heat generated by burning coal and how this is distributed across the process. Data comes from the actual process variables, obtained from the control system using OLE for Process Control, which operates using experimental data and variables that are assumed to be constant. The resulting model is fitted with two tools: least squares and Infinite Impulse Response filter of first order. It validates and verifies the model and its settings using two statistical tools: box and whisker diagram and method of eight statistical metrics related by a fuzzy function. The use of these tools evidence satisfactory performance of the proposed model.

Keywords : kiln; energy balance; least squares; IIR filters; clinker; horno rotatorio; balance de energía; mínimos cuadrados; filtros IIR; clinker.
