The calciner preheats the raw material to about 900°C (1650°F) The calcination process is completed in the kiln, which heats the material to about 1200°C (2200°F) To achieve these temperatures, fuel is added to the kiln’s main burner – and at the calciner level “Because the quality of raw material and the heat value of coal isA nearby cement kiln will substitute this plasticrich fuel for 30% of the coal it has been using The more solutions, the merrier, Agilyx’s Vaillancourt saysShould plastics be a source of energy?
