Practical operating experience in combustion of refuse derived fuel in fluidised bed hot gas generators and shell boilers

Abstract

A range of fluidised bed hot gas generators and boilers have been developed by Babcock Worsley in collaboration with the UK National Coal Board. Although the designs were developed for coal firing they have been found to be satisfactory for RDF. Hot gas generators burning EDF are operating on a green crop dryerand two EDF preparation plants. A horizontal fluidised bed boiler has been operatedon EDF. A description is given of the furnace and boiler designs and the practical operating experience of burning RDF.
