Description
Demonstration of Advanced Boiler Instrumentation Technologies Technical Report by EPRI includes New and increasing limits on emissions (in particular, NOx) and new emphasis on heat rate have underscored the need to measure flue gas constituents more accurately and in more locations. Utilities are making large capital investments in boiler improvements and emission control devices. These investments can be enhanced through the use of innovative, on-line instrumentation closer to the furnace combustion zone. Traditionally, sensors for flue gas.
constituents, such as NOx and CO, are implemented as part of a continuous emissions monitoring system (CEMS), some of which might be installed far downstream of the combustion process. This creates a significant time delay in the measurements and hinders accurate feedback based on individual unit performance
