Abstract: The present invention is generally related to a system and method that efficiently and effectively removes mercury, dioxin, and furan while also reducing granule activated carbon (“GAC”) bed fires on high temperature municipal fluid bed sludge incinerators. In this manner, the United States Environmental Protection Agency (EPA) Maximum Achievable Control Technology LLLL (“MACT LLLL”) emission limits on mercury, dioxin, and furans can be met for new high temperature fluid bed municipal sludge incineration plants, while the likelihood of GAC fires can be reduced.
