| description | The calorific power of wood of huizache (Acacia farnesiana), maguey (Agave salmiana), nopal (Opuntia streptacantha), garambullo (Myrtillocactus geometrizans) and cardon (Pachycereus sp) from arid areas of Mexico, which are often used for heating water and cooking food in rural areas, in this work are presented. The calorific power determination was carried out by means a calorimetric combustion pump and of a gravimetric thermal analysis, GTA and differential thermal analysis technique, DTA, which is quite similar to the differential scanning calorimetry (DSC). In general, the results showed that the calorific value estimated by analysis (GTA-DTA) is in all cases slightly lower than those estimated with a calorimetric pump, but in general, both results are very close between each other. Maximum variation between these values is within ± 5%, which is associated in a range within the uncertainty of the measurements made. For the nopal wood, it was found that the calorific value, estimated by GTA-DTA, reaches (11 275 kJ/kg), resulting very similar to the value determined with a calorimetric pump, (11 605 kJ/kg). In the other cases studied a greater discrepancy between the measured values was found. The elementary analysis of the woods and their ashes estimated by means of X-ray photoelectron spectroscopy (XPS), allows the determination of the carbon intensity of the woods, and indicates that there is no evidence of toxic metals such as those from coal, which shows that these woods are a sustainable and renewable product, when they are available for combustion and heat energy obtainment. |

En este trabajo se determina el poder calorífico de maderas de huizache (Acacia farnesiana), maguey (Agave salmiana), nopal (Opuntia streptacantha), garambullo (Myrtillocactus geometrizans) y cardón (Pachycereus sp) que provienen de zonas áridas de México y que suelen utilizarse para el calentamiento de agua y cocción de alimentos en el medio rural. La determinación de los poderes caloríficos se realizó por medio de las técnicas de análisis térmico gravimétrico y la técnica de análisis térmico diferencial, ATG-ATD, que es similar a la calorimetría diferencial de barrido (DSC), y mediante una bomba calorimétrica de combustión. En general, los resultados mostraron que el poder calorífico estimado por análisis (ATG-ATD) resulta en todos los casos ligeramente menor que lo estimado con bomba calorimétrica, pero en general son muy próximos entre sí. La máxima variación entre dichos valores en ± 5% se asocia en un intervalo dentro de la incertidumbre de las mediciones realizadas. Para la madera de nopal se encontró que el poder calorífico estimado por ATG-ATD alcanza 11 275 kJ/kg, resultando muy parecido al valor determinado con bomba calorimétrica, 11 605 kJ/kg. En los otros casos estudiados se encuentra una mayor discrepancia entre los valores medidos. El análisis elemental de las maderas y de sus cenizas permite la determinación del parámetro energético ambiental denominado intensidad de carbono de las maderas. Este se estima por medio de espectroscopía de fotoelec-trones emitidos por rayos X (XPS), lo que indica que no hay evidencia de metales tóxicos como los provenientes del carbón; esto demuestra que estas maderas son un producto sutentable y renovable cuando están disponibles para la combustión y obtención de energía calorífica.
