Abstract: The thermal conductivity of pulverised-fuel ash cenospheres has been determined using both a transient and a steady-state method. The effect of mechanical loading has been investigated, and the results show that the application of considerable loads is without appreciable effect on the insulating properties. Over the range 25 to 80°C, the presence of moisture adsorbed from the atmosphere gave rise to an increase of the effective thermal conductivity of the material, and this should be taken into account if cenospheres are to be used for thermal insulation.
