Life Cycle of Metals in Coal Combustion: Metal Release and Capture, Speciation in Flyash, and Transformations During Ash Reuse and Storage

An improved understanding of the factors controlling the life cycles of metals is necessary to design effective strategies to reduce metal releases to the environment. Metals of interest include arsenic, lead, mercury, and selenium.

Task 1: Metal Capture During Combustion

Task 2: Relating Metal Speciation to Leachability

Task 3: Fate of Metals During Ash Reuse and Storage

Project summary

The proposed project will investigate the life cycle of metals during coal utilization. Effective management of this life cycle is critical to limiting emissions of metals to the atmosphere and preventing their release to the environment during the reuse and storage of coal fly ash. The project objectives are to develop the scientific basis for understanding the fate of metals at different stages of coal utilization and to identify means of mitigating metal releases to the environment.
