Title: The Role of Coal Properties on the Chemical and Physical Transformation of Mercury During Post Combustion

Date: Thursday, February 26, 2004, 3:30 pm
Ben Bandy Conference Room
Center for Applied Energy Research


ABSTRACT

Several factors have been shown to affect mercury emission and speciation from coal-fired power plants. Western Kentucky University has used the Ontario Hydro Method and the semi-continuous mercury monitor to analyze mercury emissions from over 16 power plants with 10 unique unit configurations. The differences in unit configuration include combustion technologies, as well as air pollution control devices. WKU investigated the effects of chlorine, sulfur, iron, ash, and LOI on mercury emissions from different unit configurations. The results showed a link between flue gas mercury speciation and chlorine and sulfur content. The LOI had a correlation coefficient of over 0.70 with a decrease in mercury emissions.
