Contents Notes
This development project addresses the sensing and measurement of carbon fibers moving in ventilating ducts or exhaust stacks of incinerators. The sensor system employs a series of five electrically charged grids with different grid spacings for sensing fibers, determining their lengths, and presenting a count of the fibers detected. The system senses carbon fibers shorter than 0.1 mm moving at velocities from 2 to 4 m/s and measures fiber populations of up to 100 fibers/m3 in each of five lengths ranging from 0.1 mm to 1.5 mm. Areas requiring further development are identified, as are design requirements, alternative materials and fabrication techniques for producing a unit to be evaluated in a field test. In a companion development project, a mobile flow test facility was produced for evaluating and calibrating instrumentation to measure fibrous aerosols.
