Ash Handling Capacity at 65% ash handling system availability: a worked example

Suppose ash handling system availability falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate ash handling capacity for waste-to-energy equipment using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Ash discharged per conveyor cycle: 4 units / cycle (held at the documented default)
  • Conveyor cycles available per shift: 480 cycles (held at the documented default)
  • Ash handling system availability: 65 % (the input this scenario stresses; the baseline uses 90)
  • Clean-separation first-pass yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross ash handling capacity = ash handling capacity output per cycle × available ash handling capacity cycles.
  • Good ash handling capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross ash handling capacity works out to 1,920 units at these inputs.
  • Ash handling capacity downtime loss works out to 672 units at these inputs.
  • Ash handling capacity yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where ash handling system availability sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • It computes good ash handling capacity as gross conveyor capacity scaled by system availability and clean-separation first-pass yield. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Good ash handling capacity: 1,211 units (headline result)
  • Gross ash handling capacity: 1,920 units
  • Ash handling capacity downtime loss: 672 units
  • Ash handling capacity yield loss: 37.44 units
