Cement Kiln Energy Cost with kiln connected electrical or fuel-equivalent load of 2,100 kW: a worked example

What does the result look like when kiln connected electrical or fuel-equivalent load reaches 2,100 kW? The full calculation is worked below with real intermediate numbers. a kiln team needs to estimate energy cost for a firing, clinker campaign, or production day

The inputs for this scenario

  • Kiln connected electrical or fuel-equivalent load: 2,100 kW (raised for this scenario; the documented default is 850)
  • Kiln firing runtime: 24 hr (unchanged)
  • Blended kiln energy rate: 0.11 $ / kWh (unchanged)
  • Clinker or fired product output: 1,600 tons (unchanged)

Working through the calculation

  • Applying the documented formula (Energy used = equivalent load × runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 5,544 $ energy cost for cement kiln energy cost, the number this scenario is built around.
  • At this operating point the engine returns 50,400 kWh for cement kiln energy cost energy used.
  • At this operating point the engine returns 3.47 $ / piece for cement kiln energy cost cost per ton.
  • At this operating point the engine returns 231 $ / hr for cement kiln energy cost hourly cost.

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 147% above the baseline at 5,544 $ energy cost.
  • A figure at this level is achievable when kiln connected electrical or fuel-equivalent load is genuinely sustained, not just peaked for a shift. It assumes a steady-state load over the full runtime; real kilns draw far more during heat-up and idle differently during slowdowns, so a single average load will understate transient peaks.
