Under current U.S. EPA guidelines, particularly the Clean Air Act Amendments, stack gasses and the solid products of combustion require specialized treatment for removal of trace metals. This book presents a data-intensive assessment of the fate of trace metals during combustion. The data are derived from actual operating combustion systems, and the text emphasizes case studies that document trace metal fate control. Issues covered include metal volatility, metal reactions, and trace metal management through the enhancement or inhibition of specific chemical reactions.
