A state-of-the-art municipal Waste-to-Energy (WTE) combustor began operation in the town of Wainwright, Alberta, Canada in 1995. The combustor design utilizes a radiant waterwall, multichamber, multi-stage combustor design, followed by a convective boiler section, a flue gas economizer and an air to air heat exchanger. The air pollution control system consists of an all dry lime injection system followed by a fabric filter collector. The system has the capability for delivering activated carbon, if needed, for the control of various pollutants. The pulse-jet fabric filter collector utilizes GORE-TEX{reg_sign} membrane/TEFLON{reg_sign} B fiberglass filter bags for highly efficient capture of the Particulate Matter (PM), which includes lime reaction and absorbent products, unreacted lime, and fly ash which is rich in trace metals and other fine particulates. Compliance testing revealed that the system is providing low outlet emission levels and would meet the proposed US EPA New Source Performance Specifications for Municipal Waste Combustor`s in the US for all categories. This includes acid gases, trace heavy metals, including Pb, Cd, Hg, and PCDD/PCDF as measured by toxic equivalency factors. PM levels were measured at 9.8 mg/Rm{sup 3}. Lead, cadmium and mercury emission levels were measured at 0.37 {micro}g/Rm{sup 3}, < 0.001 {micro}g/Rm{sup 3}, and 0.24 {micro}g/Rm{sup 3} respectively. PCDD/PCDF emissions were measured to be 0.044 {micro}g/Rm{sup 3} (TEQ). Finally, HCl and SO{sub 2} emissions were measured to be 11 mg/Rm{sup 3} and 13 mg/Rm{sup 3} respectively.
