Assessment of Instrumentation and Analytical Techniques for High Temperature in Situ Waste Stream Characterization of Industrial Flue Gases

摘要

This report is a survey of commercial and research instrumentation as applicable to the measurement of flue gas constituents. The importance of instrumentation in measuring pollutants from flue gas streams has long been recognized. However, only in recent years has the possibility of in situ measurement of all flue gas species been explored. The point of focus had been on pollutants but has shifted to corrosive and fouling constituents of flue gas streams. It is important to identify these species in situ before they change to more stable species. This is the major shortfall of commercial instrumentation. The reasons for this shift is because of the high maintenance costs of heat recuperation equipment caused by these fouling and corrosive species. The instrumentation in this report are reviewed with this criteria in mind. The advantages and disadvantages of each type are discussed as well as sampling and calibration problems associated with each. Some of the possible constituents of various flue gas streams are also discussed. It is known that some of the constituents of flue gas streams have been identified as corrosive or fouling species of flue gas streams have been identified as corrosive or fouling species, but there are many more that need to be identified and classified. Recommendations for further work in this area are discussed. (ERA citation 12:005173)
