Cyclone Efficiency at 99% target cyclone collection efficiency: a worked example

What does the result look like when target cyclone collection efficiency reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when checking cyclone separator performance, precleaner loading, cut point assumptions, or downstream filter protection.

The inputs for this scenario

  • Captured solids mass: 880 lb (unchanged)
  • Inlet solids mass: 1,000 lb (unchanged)
  • Target cyclone collection efficiency: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Cyclone collection efficiency = captured solids mass ÷ inlet solids mass × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 88 % for cyclone collection efficiency, the number this scenario is built around.
  • At this operating point the engine returns 11 points for cyclone efficiency gap to target.
  • At this operating point the engine returns 880 count for captured solids mass.
  • At this operating point the engine returns 1,000 count for inlet solids mass.

How this compares with the baseline

  • Against the tool's baseline example, where target cyclone collection efficiency sits at 90% and the headline result is 88 %, this scenario lands almost exactly on the baseline at 88 %.
  • A figure at this level is achievable when target cyclone collection efficiency is genuinely sustained, not just peaked for a shift. Mass-based efficiency is an overall number; it hides the fine-particle fractional efficiency that actually drives stack emissions and filter loading.
