Engineering feasibility study of new gas technologies for waste-to-energy boilers to improve operational and environmental characteristics. Topical report, September 1986-February 1987

New gas technologies to improve the operational and environmental characteristics of waste-to-energy boilers were evaluated. The study indicated that further reductions of PIC emissions from these boilers, which are an important public-health concern, may be achievable through improved control of the combustion process in the furnace. A conceptual design of a distributed-burner system and more-sophisticated combustion controls, expressly designed for PIC reduction, is presented. Also presented is a conceptual design of an ash afterburner system intended to detoxify the fly-ash waste stream, where PIC tend to concentrate.
