Nonwoven Materials & Technical Textiles worked example

Bonding Energy with bonding line connected load of 30 kW: a worked example

Push bonding line connected load up to 30 kW and the picture changes. This example computes every intermediate figure at that operating point. Use it when bonding energy in nonwoven materials and technical textiles is being quoted and energy is a real chunk of the nonwoven materials and technical textiles cost stack.

The inputs for this scenario

  • Bonding line connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Bonding line 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 bonding energy cost = bonding energy connected load × bonding energy runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for bonding energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total bonding energy cost.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per kwh.
  • At this operating point the engine returns 3.6 $ / hr for hourly bonding energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where bonding line connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • It computes total bonding energy in kWh and its cost from connected load, runtime, and rate, then divides cost by units processed to give a per-unit energy figure. 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.
