Cement Kiln Energy Cost with kiln connected electrical or fuel-equivalent load of 430 kW: a worked example

This worked example runs the cement kiln energy cost numbers for a tougher week than the baseline: kiln connected electrical or fuel-equivalent load of 430 kW instead of the typical 850 kW. Estimate kiln energy cost and cost per ton for cement clinker or fired building materials.

The inputs for this scenario

  • Kiln connected electrical or fuel-equivalent load: 430 kW (the input this scenario stresses; the baseline uses 850)
  • Kiln firing runtime: 24 hr (held at the documented default)
  • Blended kiln energy rate: 0.11 $ / kWh (held at the documented default)
  • Clinker or fired product output: 1,600 tons (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Energy used = equivalent load × runtime.
  • Cement Kiln Energy Cost works out to 1,135 $ energy cost at these inputs, and this is the headline figure for the scenario.
  • Cement Kiln Energy Cost energy used works out to 10,320 kWh at these inputs.
  • Cement Kiln Energy Cost cost per ton works out to 0.71 $ / piece at these inputs.
  • Cement Kiln Energy Cost hourly cost works out to 47.3 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where kiln connected electrical or fuel-equivalent load sits at 850 kW and the headline result is 2,244 $ energy cost, this scenario comes in 49.41% below the baseline at 1,135 $ energy cost.
  • Use it when budgeting a kiln campaign, evaluating a fuel switch, or attributing energy cost to a specific clinker batch or shift. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Cement Kiln Energy Cost: 1,135 $ energy cost (headline result)
  • Cement Kiln Energy Cost energy used: 10,320 kWh
  • Cement Kiln Energy Cost cost per ton: 0.71 $ / piece
  • Cement Kiln Energy Cost hourly cost: 47.3 $ / hr
