Abstract:

The range of coals encountered by new and existing power stations in the UK and abroad is steadily increasing. The inorganic component - the mineral matter - of coal impacts directly on plant availability through coal ash slagging, emission limits especially for fine particulate material and ash use and disposal. These factors constrain the acceptable range of coals for power station use. This project addresses the lack of fundamental understanding of the processes and rates of coal ash formation. It also considers the inability to predict boiler ash properties and behaviour because of a lack of detailed numerical descriptions for fly ash. The objectives of this project are:

To improve understanding of the transformations undergone by major coal minerals during pulverised coal combustion

To provide quantitative data on the rates of coal mineral transformations

To provide quantitative descriptions of boiler ashes, especially finer ash particles, for modelling boilers and precipitators using computational fluid dynamics

To improve understanding of the effect of coal mineral transformations on the processes of boiler ash formation, deposition, emission and disposal
