Dry Flue Gas Cleaning Processes for Achieving Air Pollutant Emissions Requirements.

摘要

The paper discusses both municipal waste combustor (MWC) rules and basic dry flue gas cleaning (FGC) processes, and compares the performance of the latter using field test data. Methods to supplement dry FGC processes for improving the control of mercury and organics are addressed. Dry FGC processes can meet requirements for regulated air pollutants from MWCs: acid gas, trace organic, trace heavy metal, and particulate emissions. Rules for controlling these and nitrogen oxide emissions from MWCs with a capacity over 225 tons/day were published by the U.S. EPA in early 1991 in compliance with the Clean Air Act Amendments (CAAA) of 1990.
