Fine and Coourse Particulate Continuous Emissions Monitoring
This project will demonstrate the feasibility and practicaity of applying beta attenuation monitors (BAM) to quantify hourly concentrtions of PM2.5 (particoes<2.5 um) and corase (PM 10-2.5) the difference between PM10 and PM 2.5 mass concentrations where PM10 refers to particles with aerodynamic diameter <10um) in diluted extracts from stacks at HWCs. BAM's quarterly mass by measuring the reduction is flux of electrons generated by a redioactive source through a filter tape that commects particles.EPA needs PM2.5 and course continuous emissions monitors (CEMS) to better estiate and control emissions thataffect public health, visibility, and climate. Although BAM's ae widely used fior abient PM2.5 monitoring, they exhibit differences with respect to filter samples depending on the composition of the particles collected. These differences are exacerbated in source samples owing to the large fraction of semi-volatile material and hygroscopic components, like sulfates. Modern CEMS must be able toaccurately quantify PM mass in emissions with high moisture contents and with condensable and semi-volitile compounds. These CEMS should pass PS11 performance specifications and also be equivalent to PM2.5 measured by dilution stack samplers that are being developed by EPA to better represent PM as it would appear after dilution and cooling. Stack dilutionsampling for PM2.5 is widely recognized as a better approach than hot-stack sampling to represent PM effects measurement of PM2.5, PM10-2.5, and other variables such as black carbon (BC) in a package easily mounted at a smpling port and for obtaining accurate data with minimal operator intervention. This project will mate a newly developed BAM that simultaneously measures PM2.5, PM10-2.5, and BC with an extraction-dilution system. Through testing of simulated stack samples, it will quantify the extent to which such a configuration can accurately portray mass concentrations as they app0ear in the atmosphere immediatly after cooling. This testing feasibility testing will be translated into a practical design, applicable to a wide number of incinerator waste inputs, operating conditionas, and stack configurations in anticipation of a Phase II proposal to develop a commercial prototype. The design intends to meet PS-11 Performance Specifications. EPA CTM-039 will be used as a guideline for the prototype design. Phase 3 will cary the prototype to a commercial product.
