Cathode Active Material & Precursor Manufacturing worked example

Calcination Energy with calcination kiln load of 30 kW: a worked example in cathode active material & precursor manufacturing

What does the result look like when calcination kiln load reaches 30 kW? The full calculation is worked below with real intermediate numbers. Use it when calcination energy in cathode active material and precursor manufacturing is being quoted and energy is a real chunk of the cathode active material and precursor manufacturing cost stack.

The inputs for this scenario

  • Calcination kiln load: 30 kW (raised for this scenario; the documented default is 12)
  • Kiln firing runtime: 8 hr (unchanged)
  • Energy price: 0.12 $ / kWh (unchanged)
  • Accepted CAM output: 1,000 kg CAM (unchanged)

Working through the calculation

  • Applying the documented formula (Calcination energy cost = calcination kiln load × kiln firing runtime × energy price) to the inputs above produces each figure below.
  • At this operating point the engine returns 28.8 $ for calcination energy cost, the number this scenario is built around.
  • At this operating point the engine returns 240 kWh for calcination energy used.
  • At this operating point the engine returns 0.03 $ / piece for calcination energy cost per kg cam.
  • At this operating point the engine returns 3.6 $ / hr for hourly calcination energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where calcination kiln load sits at 12 kW and the headline result is 11.52 $, this scenario comes in 150% above the baseline at 28.8 $.
  • A figure at this level is achievable when calcination kiln load is genuinely sustained, not just peaked for a shift. It uses average connected load over the firing window, so it won't capture the difference between ramp-up, soak and cool-down power draw unless you supply a true energy-weighted average kW.
