Disposal and utilisation of ash residues from pressurised fluidised bed combustion
A study has been carried out to assess the environmental effects of disposing of pulverised fluidised bed combustion (PFBC) ash, to consider suitable ash disposal schemes and to investigate its possible utilisation in commercial outlets. This system is evaluated as an alternative to the existing pulverised fuel (PF) generation system. Factors considered in the report include the chemical composition of the ash, the concentration of trace elements, the behaviour and environmental impact of the leachate. Plant growth experiments were undertaken in a greenhouse and in a field to investigate constraints on vegetation establishment and growth. Despite poor growth conditions, it was concluded that, with the use of top soil or amendments, successful restoration and landscaping of PFBC ash disposal sites should be achievable.
