Procedair dry scrubber supplied for a 100 tpd waste to energy plant in Canada

An overview of the Air Pollution Control system at Canada's most recently retrofitted Energy-from-Waste facility is presented. The plant burns 100 tons per day of municipal solid waste in three modular incinerators, which are ducted to a common system for steam generation, heat recovery, and APC. Procedair Industries Inc. provided an All-Dry Scrubbing System for the APC, consisting of a custom-designed venturi reactor, fabric filter, and reagent handling system. The reagent is hydrated lime and the filter bags are woven fiberglass with a Teflon '8' finish. The system is designed for 35, 100 Nm3 /hr of flue gas at 138 to 184'F, and high concentrations of particulates and acid gases. Performance objectives included up to 95% removal efficiency in particulates, doixions/furans, and HCI concentration, and 80% reduction in S02' The system has been operating successfully since early 1997, and recent stack testing has shown that key performance targets are being easily met.
