Assessing the self-heating behaviour of Callide coal using a 2-metre column

A 2-m, adiabatic column has been successfully refurbished and recommissioned for coal self-heating research at The University of Queensland. Subbituminous coal from the Callide Coalfields reached thermal runaway in just under 19 days from a starting temperature of 20-22 degreesC. The coal was loaded as two layers, with an R-70 index of 2.73 degreesC h(-1) and 5.90 degreesC h(-1) for the upper layer and lower layer respectively. Initially, a hotspot developed in the upper layer between 120 and 140 cm from the air inlet due to moisture adsorption. After 7 days, self-heating in the lower half of the column began to take over, consistent with the higher R-70 index of this coal. The location of the final hotspot was approximately 60 cm from the air inlet. Further tests on Australian coals, with the column, will enable a better understanding of coal self-heating under conditions closely resembling mining, transport and storage of coal. The results from the column will also provide industry with the information needed to manage the coal self-heating hazard. (C) 2002 Elsevier Science Ltd. All rights reserved.

Grupo Per??metre

En nuestro mundo, todos los grandes proyectos surgen por una gran idea en la mente de una persona que encuentra otras personas dispuestas a secundarla. La creaci??n de los grupos de did??ctica tambi??n sigue la misma l??nea. El objetivo es contar c??mo surgi?? en 1992 el Grupo Per??metre, un grupo formado por maestros y profesores amantes de las matem??ticas y preocupados por su did??ctica. Lo que en principio fue una reuni??n para compartir ideas, dificultades y preocupaciones dio lugar a un movimiento de renovaci??n que a??n se mantiene en nuestros d??as. Desde el principio, uno de los aspectos primordiales fue el intercambio de experiencias, lo que nos llev?? a extrapolarnos del grupo para organizar una serie de jornadas matem??ticas. Se ha dividido esta historia en dos partes, por un lado el pasado con el comienzo del grupo, y a continuaci??n el presente de un grupo que contin??a con sus objetivos iniciales totalmente vigentes.
