| Abstract |
The report describes the development and calibration of a five-stage cyclone system, designed and fabricated by Southern Research Institute. The system was calibrated using both a vibrating-orifice aerosol generator (to generate mono-disperse, large-diameter dye particles for use at ambient and higher temperatures) and a pressurized Collison nebulizer (to disperse monodisperse, small-diameter latex particles for use at ambient temperature). Results from calibrating the cyclones at several conditions of flow, temperature, and particle density suggest that the D(50) cut points are proportional to the gas flow rate raised to a negative exponent which is between -0.63 and -1.11, linearly proportional to the gas viscosity, and proportional to the reciprocal of the square root of the particle density. At 25 C, 28.3 liters/min, and for a particle density of 1.0 g/cc, the D(50) cut points were 5.4, 2.1, 1.4, 0.65, and 0.32 micrometers for cyclones I-V, respectively. |
