Wood & Paper Manufacturing worked example

Paper Machine Speed with paper machine speed connected load of 30 kW: a worked example

This scenario runs the paper machine speed calculation on the strong side: paper machine speed connected load of 30 kW, with every other input held at its documented default. Use it when paper machine speed in wood and paper manufacturing is up for an upgrade and you want a defensible savings story.

The inputs for this scenario

  • Paper machine speed connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Paper machine speed runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Units processed during runtime: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total paper machine speed energy cost = paper machine speed connected load × paper machine speed runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 28.8 $ for total paper machine speed energy cost, the number this scenario is built around.
  • At this operating point the engine returns 240 kWh for paper machine speed energy used.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per unit.
  • At this operating point the engine returns 3.6 $ / hr for hourly paper machine speed energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where paper machine speed connected load sits at 12 kW and the headline result is 11.52 $, this scenario comes in 150% above the baseline at 28.8 $.
  • Use it to price machine energy into product cost, compare grades or speeds, or size the savings from a drive or vacuum efficiency upgrade. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
