| description | Morphological and structural characterization of fly ash powder's reports are obtained from coal combustion supplied by the thermal - electrical plant Termotasajero S.A. The morphological study consisted in the superficial analysis, using Scanning electron microscopy (SEM). The basic chemical composition was found using X ray energy dispersion spectrums (EDX - SEM) whereas structural characterization was developed by X-ray diffraction (XRD). The software Image tool V. 3.0. was used for the particle size distribution. The results obtained show that the fly ash powders are composed mostly by spherical particles as well as unburned particles adhered to the particles, with average particle size of order micrometers. The structural study, using XRD, reports the main crystalline phases of mullite, quartz and hematite. Our results will allow us to evaluate the Thermal - electrical Plant Termotasajero's coal combustion processes, as well as another uses and applications of those ashes. |

Se reporta la caracterización morfológica y estructural de polvos de cenizas volantes obtenidos de la combustión de carbón, suministrados por la Central Termoeléctrica Termotasajero S.A. El estudio morfológico consistió en el análisis superficial mediante el uso de microscopia electrónica de barrido (MEB). La composición química elemental fue hallada usando los espectros de dispersión de energías de rayos X (EDS-MEB), mientras que la caracterización estructural se llevó a cabo por difracción de rayos X (DRX). Para la distribución del tamaño de partícula se usó el software Image Tool V. 3.0. Los resultados obtenidos muestran que los polvos de cenizas volantes están formados por partículas mayoritariamente esféricas (cenosferas y plerosferas), así como de partículas de inquemados adheridas a las partículas de ceniza, con tamaño de partícula promedio del orden de micrómetros. El estudio estructural, para el cual se utilizó DRX, reporta las fases cristalinas mayoritarias de la mullita, cuarzo y hematita. Nuestros resultados permitirán evaluar los procesos de combustión del carbón de la Central Termoeléctrica de Termotasajero, así como otros usos o aplicaciones a dichas cenizas.
