Waste-to-Energy Equipment worked example

Emissions Control Load with flue-gas cleaning connected load of 30 kW: a worked example

This scenario runs the emissions control load calculation on the strong side: flue-gas cleaning connected load of 30 kW, with every other input held at its documented default. Use it when emissions control load in waste-to-energy equipment is up for an upgrade and you want a defensible savings story.

The inputs for this scenario

  • Flue-gas cleaning connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Emissions control runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Waste units processed during runtime: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total emissions control load energy cost = emissions control load connected load × emissions control load runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for emissions control load energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total emissions control load 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 emissions control load energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where flue-gas cleaning connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • Use it when quantifying parasitic load on net power export, budgeting abatement operating cost, or comparing the energy penalty of different flue-gas cleaning configurations. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Emissions control load energy used: 240 kWh (headline result)
