Kiln Utilization Cost at 94% kiln load efficiency: a worked example

Push kiln load efficiency up to 94% and the picture changes. This example computes every intermediate figure at that operating point. a kiln scheduler needs to decide whether a firing load uses enough kiln capacity to justify running the cycle

The inputs for this scenario

  • Usable kiln cycle hours: 28 kiln hr (unchanged)
  • Cost per kiln hour: 185 $ / kiln hr (unchanged)
  • Kiln load efficiency: 94 % (raised for this scenario; the documented default is 82)
  • Fixed firing-cycle cost: 950 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Utilized kiln-hour value = usable kiln hours × cost per kiln hour × kiln load efficiency) to the inputs above produces each figure below.
  • At this operating point the engine returns 5,819 $ kiln cost for loaded kiln utilization cost, the number this scenario is built around.
  • At this operating point the engine returns 208 $ / kiln hr for cost per kiln hour.
  • At this operating point the engine returns 4,869 $ kiln cost for utilized kiln-hour value.
  • At this operating point the engine returns 950 $ for fixed firing-cycle cost.

How this compares with the baseline

  • Against the tool's baseline example, where kiln load efficiency sits at 82% and the headline result is 5,198 $ kiln cost, this scenario comes in 11.96% above the baseline at 5,819 $ kiln cost.
  • It computes the utilized value of a firing's kiln hours after load efficiency, then adds the fixed firing-cycle cost for a total loaded kiln cost. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Loaded kiln utilization cost: 5,819 $ kiln cost (headline result)
  • Cost per kiln hour: 208 $ / kiln hr
  • Utilized kiln-hour value: 4,869 $ kiln cost
  • Fixed firing-cycle cost: 950 $
