Cyclone Efficiency at 65% target cyclone collection efficiency: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target cyclone collection efficiency to 65%, then walk the calculation through step by step. Calculate cyclone collection efficiency from captured solids, inlet solids, and target collection efficiency.

The inputs for this scenario

  • Captured solids mass: 880 lb (held at the documented default)
  • Inlet solids mass: 1,000 lb (held at the documented default)
  • Target cyclone collection efficiency: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Cyclone collection efficiency = captured solids mass ÷ inlet solids mass × 100.
  • Cyclone collection efficiency works out to 88 % at these inputs, and this is the headline figure for the scenario.
  • Cyclone efficiency gap to target works out to -23 points at these inputs.
  • Captured solids mass works out to 880 count at these inputs.
  • Inlet solids mass works out to 1,000 count at these inputs.

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 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target cyclone collection efficiency, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Mass-based efficiency is an overall number; it hides the fine-particle fractional efficiency that actually drives stack emissions and filter loading.
