Engineering Feasibility Study of New Gas Technologies for Waste-to-Energy Boilers to Improve Operational and Environmental Characteristics

摘要

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.
