## CYCLONE
- Cut-particle diameter, d50, and similarly d80, d90, d95 and d99
- The complete efficiency curve, or the
**Tromp**curve - The overall cyclone collection efficiency
- Pressure drop
The software is
available in two versions : simulation-version and design-version.
In the design-version, the inputs required are:
- Number of cyclones (you can even design for twin cyclones or more than two cyclones)
- Inlet gas flow rate, temperature and molecular weight of the gas (gas may or may not be air)
- Inlet solids flow rate and particle density (with this, gas/solid ratio gets determined)
- Plant elevation from sea-level
- Inlet feed particle size distribution
- Entrance velocity (you can choose the optimum practical value by taking out predictions for a few values)
Based on the
above inputs, the following parameters are predicted:
- Cyclone design dimensions and collection hopper design dimensions
- Cut-particle diameter of the cyclone, d50. The values of d80, d90, d95 and d99 are also predicted.
- Pressure drop
- Collection
efficiency of individual size fractions. This
**Tromp**curve is also automatically generated in a graph. - Total collection efficiency and outlet dust loading
- The entered feed particle size distribution is also depicted graphically.
While the above
design-version is useful to obtain the dimensions, practical
considerations may sometimes dictate slightly different dimensions from those
calculated. Alternately, you may like to choose some dimensions rounded
off to nearest desirable integers. For such cases, simulation-version
would be useful wherein the cyclone dimensions would be entered instead of the
entrance velocity with all other inputs being the same as above.
In the design version of the software, the cyclone dimensions are calculated from a user-specified entrance velocity. For the cyclone so designed, the above mentioned performance parameters are also predicted. The software has in-built database management functions facilitating a record-keeping of all the cyclones designed/analysed. The companion software CLASANAL
is useful to determine the cyclone performance parameters d50, Tromp curve, direct bypass
fraction and sharpness index of cut from the measured particle size distributions
