Waste-to-Energy Equipment worked example

Furnace Throughput at 65% furnace availability: a worked example

Suppose furnace 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 furnace throughput 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

  • Waste charged per grate cycle: 4 units / cycle (held at the documented default)
  • Grate cycles available per campaign: 480 cycles (held at the documented default)
  • Furnace availability (online time): 65 % (the input this scenario stresses; the baseline uses 90)
  • Complete-burnout first-pass yield: 97 % (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where furnace 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 furnace throughput as gross grate capacity multiplied by furnace availability and complete-burnout 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.
