Monitoring of Incinerator Emissions is a chapter to be included in a book entitled Hazardous Waste Incineration, edited by A. Sarofim and D. Pershing, and published by John Wiley and Sons. The chapter describes stack sampling and analysis procedures in use on hazardous waste incinerators and other waste combustion devices. Manual methods of analysis are discussed, along with continuous emission monitoring systems. Emerging technology is described, along with discussions on quality assurance/quality control (QA/QC) and sources of information and technical support. The chapter is intended for the practicing engineer involved with combustion of hazardous waste. He or she could be a plant engineer, a contractor planning a test burn, or a researcher evaluating performance of developmental or established equipment or procedures. The chapter should also be useful to a variety of other readers.
