A previous IEA CCC report entitled Understanding slagging and fouling during pf combustion by Gordon Couch presented a comprehensive review of the topic at that time. The report summarised the ‘state of knowledge’ in respect of boiler design and operation, ash formation and deposition, predictive techniques and remedial measures. A later IEA CCC report, also by Gordon Couch entitled Ash management in coal-fired power plants, covering a number of ash-related issues, addressed some of the more recent developments in the field of slagging and fouling but a number of significant changes have continued to reshape the power generation sector which warrant this updated study of the topic. This report sets out to consider how the
