Case Study: GORE^® REMEDIA^® Catalytic Filter Bags – Municipal Solid Waste Incineration – Kochi City Clean Center, Japan

At an energy to waste facility in Kochi, Japan, power was generated by incinerating municipal waste using a stoker furnace, which incorporated pollution control units at the downstream. After heat recovery, the flue gas was further cooled down to 150 °C for the effective carbon adsorption of dioxin/furan. The gas was then passed through a filter baghouse to remove particulates. Finally, the gas was reheated to 210 °C for tail-end NOx reduction by an SCR tower. This flue gas treatment process was neither energyefficient nor cost-effective, and the plant management was looking for a partner to recommend and implement a process change to save energy and costs.
