Assessment Of Ash Re-Firing And Mineral Addition - Impact On Plant Performance And Ash Disposal: Project Summary

Abstract:

<p>This document is a summary for the project titled 'Impact on Plant Performance and Ash Disposal'.</p> The specific objectives of this project were as follows:<bl> <li>To provide boiler operators with a relatively simple means of increasing cycle efficiency and reducing particulate emissions.</li> <li>To determine the optimum level of mineral additions using an Entrained Flow Reactor.</li> <li>To identify possible technical showstoppers using pilot scale combustion tests.</li> <li>To conduct a full scale ash re-firing test.</li> <li>To undertake a techno-economic assessment of ash re-firing and mineral addition and generate a set of guidelines for re-firing of pulverised fuel ash and mineral addition.</li> </bl></br> <p>This project has shown that ash re-firing is both technically and financially viable on existing coal fired power plant. It is believed that commercial scale replication of the concept could be undertaken by plant operators using the data gathered by this project as the basis for a full scale development.</p> This profile contains information on the project's: <bl> <li>Objectives</li> <li>Summary</li> <li>Background</li> <li>Mineral Addition and Ash Re-fitting Trials</li> <li>Conclusions</li> <li>Potential for Future Development</li> <li>Cost</li> <li>Duration</li> <li>Contractor</li> <li>Collaborators</li> </bl>
