Gas Turbine Engine Particulate Matter Measurement

"The primary method of particle mass measurement for industrial processes uses sampling via extraction and filtration. Long sample times are specifically a problem for measurements of industrial gas turbine engines, and as stated in the solicitation, arevirtually impractical for short term operation of military gas turbine engines. The Navy would like to find a fast and accurate substitute measurement technique for the conventional mass sampling EPA Method 5. PMC and its predecessor company, Insitechave worked to develop in-situ real time particulate instruments for the power industry for more than 15 years.Process Metrix (PMC) is currently developing an optical instrument known as the PPC (Process Particle Counter) that is ultimately directed at precisely the application described above. Indeed a prototype instrument has obtained quantitative size and massconcentrations in a variety of harsh environments, including pulp and paper recovery boilers, expanders (turbines without compressors) in the petroleum industry, and industrial gas turbines for power generation. The goal of the proposed work is toincorporate additional improvements to the PPC, demonstrating that this sensor can produce fast real-time size and mass quantitative measurements comparable to EPA method 5 in military gas turbine engine environments. PM10/PM2.5 Measurement of Particulate Matter. This optical technique can supplement or replace standard EPA method 5
