Furnace Throughput Rate at 99% target throughput rate: a worked example

What does the result look like when target throughput rate reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when production wants to know whether a furnace line is keeping pace with the schedule.

The inputs for this scenario

  • Completed furnace output: 42 loads (unchanged)
  • Scheduled furnace capacity: 48 loads (unchanged)
  • Target throughput rate: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Furnace throughput rate = completed furnace output ÷ scheduled furnace capacity × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 87.5 % for furnace throughput rate, the number this scenario is built around.
  • At this operating point the engine returns 11.5 points for gap to throughput target.
  • At this operating point the engine returns 42 loads for completed furnace output.
  • At this operating point the engine returns 48 loads for scheduled furnace capacity.

How this compares with the baseline

  • Against the tool's baseline example, where target throughput rate sits at 90% and the headline result is 87.5 %, this scenario lands almost exactly on the baseline at 87.5 %.
  • A figure at this level is achievable when target throughput rate is genuinely sustained, not just peaked for a shift. It measures volume, not quality or value; a furnace can hit target throughput while producing low-yield or low-priority loads, so it must be read alongside yield.

Results at a glance

  • Furnace throughput rate: 87.5 % (headline result)
  • Gap to throughput target: 11.5 points
  • Completed furnace output: 42 loads
  • Scheduled furnace capacity: 48 loads
