Abstract

A conical spouted bed combustor that operates from the spouted bed regime to dilute spouted bed regime (jet spouted bed) has been used in the thermal remediation of sand from Arminza beach polluted with oil from Prestige spill. Experimental study on operation in a pilot plant combustor has been carried out with beds consisting of sand with different water weight content in a wide range of operating conditions at a temperature range of 25-1000°C. Stable operating conditions of the combustor have been determined for thermal degradation of polluted sands. Combustion of sand prepared by mixing with oil and sand polluted has been carried out at 500 °C and the combustion gas composition has been analyzed.
